Assuming none of you will go tell the police, I'll tell what I did 8)
Stole a couple of stuffs from stores: Candies, games, mp3, headphones, earphones, spray cans & school supplies (Those are the ones I can remember)
Did some Breaking & Entering on rare occasions, I broke into my old high school and stole a retro projector, DVDs and a computer screen which me and my friends sold for around 2000$ in all.
Did a lot of graffiti with spray cans, markers and etches.
Did some trespassing mainly because of graffiti and going into high places where it's harder for the city people to buff off our graffiti.
Illegal drinking when I was younger.
Smoked weed once.
Aggravated Assault on a guy.
Vandalism on some property.
Illegal downloads and uploads.
Public urinating. (I never do this, heck I don't even like to pee in public toilets. I just had to pee soooo badly and there was no washroom nearby. Ironically, I pee'd beside a police station)
Disturbance of peace for the drivers, where we put huge garbage bags in the middle of road to make them do a huge detour in order to continue.
Vandalism; I broke cars, walked on cars, broke their mirrors and windows.
Surprisingly, I never got caught doing any of these, except for the time I stole from my high school, because we did it with a guy who NEVER did B&E before and he bragged about it to his classmates and eventually one of them told the cops. I didn't get convicted for it tho, I don't know what happened to that story, they just let it go I presume.
And if you're thinking, no I'm not like that anymore. Those were my rebel days and ever since I met my girlfriend, I changed. She didn't like the way I used to live and I changed my lifestyle to make her happy. Tbh, I'm glad that I abandoned that kind of lifestyle, I'm happier the way I am now.
