As a little kid....ugh thats hard....i was always a good kid when i was little...
wasn't until i turned 10 that i started causing trouble.
At age 13, I spraypainted school property and had to stay behind after school to clean it.
Age 12, i took a water gun one hot May day, pointed it through the vents of the door and just shot water all over the room.
Age 13, snuck out late at night to go hit the pool with some friends on this trip to Washington (stayed in a hotel). Came back to our hall to find the teachers/chaperones pissed that we just left when we were supposed to go to sleep. Next night they stayed out in the hallway as surveillance to watch for us. Not as badass as it sounds but you should have heard how the teachers were fuming.
Age 11, pulled the swimming shorts down of a kid who was annoying the absolute crap out me. Then pushed him in the pool. I did apologize afterwards because thats not usually my character but I did get him to finally shut up, so i was beaming a wide smile in my victory.
Age 10, stole all the cookies, candies and other sweets one late night in the camp's kitchen and stashed them in my cabin. Gave them out to my closest of friends if they asked (didn't want the whole camp knowing about it). Basically it was free at people's request. Counselors searched for them frantically for a while as i kept alternating hiding places (under the bed to under a broken floorboard, etc.). Eventually....they found it...and i got no more sweets for the rest of that camp year. Ultimate sacrifice i believe.
If i think of more ill tell you guys....i don't have many interesting stories from before i was 10 xD
