I immediately ordered a smart video door lock online and had it installed that very evening. Whenever someone passed by my apartment, the system would automatically record video footage.

The next afternoon, a notification popped up on my phone. Someone had lingered outside my door for a few seconds.

I quickly opened the app to check.`

It was a delivery driver. He left a package at my door and then headed for the elevator.

Three minutes later, another notification appeared. This time, someone had stayed outside my door for more than ten seconds.

It was Derek Sutton, the neighbor from upstairs.

I recognized him because we'd had an unpleasant misunderstanding two months earlier.

A strong gust had blown his wife's lingerie onto my balcony that day. Not wanting to touch something so personal, I'd asked her to come retrieve it herself.

To my surprise, Derek had shown up as well. The moment he saw me, he started accusing me of having an inappropriate relationship with his wife. Fortunately, she dragged him away before the situation turned into a full-blown argument.

I grabbed my phone and rushed upstairs, then pounded on his door. I knocked for quite a while, but there was no response from inside.

Finally, I raised my voice toward the door.

"If you don't come out right now, I'll expose everything you've been doing."

The next second, the door flew open. Derek stood there with an impatient look on his face.

"What is it?"

I got straight to the point. "Why are you using my address when you order food?"

He immediately played dumb. "What are you talking about? I have no idea what you mean."

"I said, why are you using my address when you order food?"

"Do you have any proof? If not, get lost." He rolled his eyes and started closing the door.

I blocked it with one hand. "Still not admitting it? Then take a look at this. Isn't that you?"

The video on my phone clearly showed him sneaking over to collect the delivery.

Seeing that, he immediately changed his story. "I'm protecting my privacy. The internet is so advanced these days. I'm just looking out for my own safety. That's not illegal, is it?"

His response was so ridiculous I almost laughed. "So protecting your privacy means making me take the blame for everything? How can you be this shameless?"

He rolled his eyes. "What's that got to do with me? If you've got a problem, call the police."

With that, he slammed the door shut.

A surge of anger rose in my chest.

So he wanted to play dirty? Then I'd make sure he didn't get a single delivery ever again.

The next day, around lunchtime, my phone alerted me that someone was outside my door again.

The delivery driver set down the order, took a photo, and left. I immediately opened the door and brought the food inside.

It was a deluxe surf-and-turf feast worth $199.

Less than two minutes after I carried it in, my phone buzzed again. I hurried over and waited by the door.

Derek didn't dare call. Instead, he sent a voice message to the driver through the delivery app.

"What's going on? Where's my food? Are you messing with me? Did you take it after you snapped the photo? I'm warning you, I spent almost two hundred bucks on that meal. Bring it back right now!"

He glanced toward my apartment a couple of times before stomping upstairs in frustration.

A few minutes later, the same delivery driver returned.

The two of them stood outside my door.

"I was in a hurry to make my next delivery. I left it here, took the photo, and left. Why would I take your food?" the driver said, looking aggrieved.

Derek wasn't interested in listening. He lit a cigarette. "My deliveries have never gone missing before. So why did it disappear when you were the one delivering it today?

"I don't care. You're paying for it. You don't want a complaint filed against you, do you? Tell you what. Give me $300 and we'll call it even."

"Why should I?!"

The argument quickly escalated.

I opened the door, still holding the takeout container in my hand.

"Are you looking for this?"

The moment they heard me speak, both of them froze.

Derek rushed over and snatched the food from my hands.

"What the hell is wrong with you? You even steal other people's food? Can't afford to feed yourself?"

I immediately turned to the delivery driver. "Hey, did you deliver it to the wrong place? My girlfriend told me she bought me lunch. When I opened the door and saw this sitting outside, I assumed it was from her."

The driver quickly pulled out his phone and checked the order several times. "No mistake. This is the twelfth floor, right? The note says to leave it here, and the apartment number is 1201."

He glanced at Derek. "You don't even live here. Why would you tell us to leave it here? You're just creating trouble for no reason."

Derek's face darkened instantly. "What the hell does it have to do with you? You're a delivery driver. Just deliver it wherever I tell you and shut up. Keep talking, and I'll file a complaint against you."

After cursing him out, Derek turned and headed upstairs through the emergency stairwell.

I thought that after this incident, he might finally learn his lesson and stop pulling this kind of stunt.

Unexpectedly, another delivery showed up outside my door that evening. I took it downstairs and tossed it into the trash along with the garbage from my apartment.

When I came back upstairs, Derek was once again standing outside my door arguing with a delivery driver.

The moment he saw me, he pointed a finger in my direction. "Was it you who stole my food? You pathetic freeloader. I caught you once at lunchtime, and now you've got the nerve to steal it again tonight?"

I played dumb. "What food? I have no idea what you're talking about."

Derek immediately turned to the delivery driver. "Well, I never got my order. If he won't admit it, then you can pay for it. Triple compensation."

Just like that, he shifted the conflict onto me and the driver.

The driver panicked and quickly turned to me. "Come on, man, don't joke around. That fried chicken cost more than $200. I don't even make that much in a day. I left it right here. You really didn't see it?

"I'm just a college student working part-time. If that order is gone, I'll basically be working for free for two days."

Meanwhile, Derek stood there with his arms folded across his chest, looking thoroughly pleased with himself. "You definitely took it. Stealing food just to survive? Looks like you really can't make ends meet."

I repeated the same trick I'd used at lunchtime and had the driver verify the address on the order.

The driver rubbed his eyes and checked it three separate times before finally confirming there had been no delivery mistake.

"This is my apartment, all right. But I didn't order any food. Why are you asking me about a missing delivery? You don't even live here."

Derek remained completely unfazed. "You know perfectly well that I always use this address. If you don't hand it over, then this kid will have to pay for it."

Then he deliberately stirred things up even further. "Don't say I didn't give you a chance. He definitely took it. If you can't get it back, then pay for it yourself."

The student driver's eyes were already welling up with tears.

I quickly tried to reassure him, "It's okay, kid. You won't have to pay a single cent. I've already called the police. We'll wait for them to get here."

Derek's expression immediately darkened. He turned as if he intended to leave.

Just then, the elevator doors opened, and two police officers stepped out.

I grabbed Derek's wrist and said coldly, "This isn't over yet. Did I say you could leave?"

On my way upstairs earlier, I'd already seen through the doorbell camera that Derek had left the delivery driver outside my apartment.

That way, if the driver decided to retaliate, he'd come after me instead. There was no way I was going to play along, so I called the police immediately.

Knowing he couldn't leave now, Derek had no choice but to come back. He even tried to accuse me first.

"Officers, he's the one who stole my delivery!"

As luck would have it, the two officers who arrived were the same ones from last time. They remembered me, which made things much easier.

"Officers, I found the person we were looking for last time." I deliberately said that part quietly before raising my voice to say, "Officers, my neighbor insists I stole his delivery, but he lives upstairs. I never even went up there.

"The delivery driver also said the address on the app was my apartment. I really don't understand what's going on.

"I did pick up a bag outside my door when I went downstairs to throw out the trash just now, but I thought it was a bag of garbage I'd left there."

The delivery driver quickly pulled out the order details and delivery records from the app.

Derek's eyes darted around as he started making things up. "I was protecting my privacy. Besides, if it wasn't yours, what gave you the right to take it?"

I let out a cold laugh. "Oh? If you wanted to protect your privacy, why didn't you have the driver leave it downstairs? Why leave it outside my apartment?

"I already took one by mistake at lunchtime and warned you about it. You still didn't learn your lesson tonight. How is that my fault?

"Besides, I usually leave garbage outside my door. Aren't you worried about your food getting dirty if you leave it there?"

As I spoke, I pulled out my phone and replayed what had happened at lunchtime.

Derek's face turned ugly. "You did this on purpose, didn't you? No wonder I had diarrhea yesterday. So it was because of you. I'm going to the hospital tomorrow, and if they find anything wrong, you'll pay for it!"

Even the officers seemed speechless at his behavior, though they couldn't say much because of their position.

I continued mockingly, "If you go dig through the dumpster downstairs now, it might still be warm."

Derek looked like he was about to explode. His eyes bulged with rage.

After piecing together the entire situation, the officers stopped humoring him.

"Sir, using someone else's address for your deliveries is also an invasion of their privacy. And she already warned you about it. You refused to change it. If your food went missing, she bears no responsibility. The loss is yours to bear.

"The driver delivered it exactly where the order instructed. Since you specifically requested that it be left at the door, don't make things difficult for him."

I smiled at the delivery driver. "You heard them. You didn't do anything wrong. Go finish your deliveries. If they deduct money from your pay, call the police and come find him."

The driver thanked both the officers and me before hurrying into the elevator.

Worried that Derek would try to pull another refund scam later, I twisted the knife a little further. "Officers, if he files for a refund again and ends up provoking a driver into coming after him, would that count as creating a public disturbance?"

The officers froze for two seconds before their expressions immediately turned serious.

"You have children at home. If you end up with a criminal record, it could affect their future opportunities."

"That's right. Delivery drivers have it hard enough as it is. You're an adult. If you make a mistake, you need to take responsibility for it yourself."

"This isn't even your first time. We couldn't find you last time, but if we have to come back again, you'll be explaining yourself at the station."

Derek opened and closed his mouth several times. Whatever he wanted to say, he ultimately swallowed it. All he could do was slink upstairs in defeat.

The delivery scam problem had finally been resolved.

What I didn't expect was that cutting off Derek's path to free meals would make him hold a grudge against me.
