Oh shit, here comes the pain. All happened from 11-13 years old. Parents got divorced at 10. In retrospect, I didn't take it well.
When i was 11, we went to the old-folks home and climbed on the roof. They had a water hose ran up there to do some maintenance so we fed the hose into someone's house through a skylight and turned it on and left. Next day, the hose was gone from that part of the roof and on another building within the same complex, we climbed that roof and fed the hose into the air-conditioner filtration unit and turned it on full and walked away. The next day, the hose was not on the roof.
Climbed roof to school. It was summer vacation and the skylight was ajar on most classrooms. We got ropes and repelled into the classroom suffering rope burns (some pretty bad.) When we were in, we got the printing ink from the copy room and destroyed the math classroom. Then took fire-extinguishers and added frosting to the ink.
Shit in the driveway and blamed it on the dog (yep, me too.) Dad called me out on it as 'human shit' and I stuck to my story. Pretty sure he hid the guns better after that and he vowed never to buy a microwave oven due to me.
Found a dead cat that was hit by a car. Tied it onto my bike with a rope and drug it around the block and through the middle of stopped commuter traffic betweek the lanes of cars. It was a hot July day and everyone had their windows down. All I remember is someone yelling "you sick asshole." We then buried it with only its paw sticking up out of the ground. Of course, we were all laughing at the time hysterically.
Would run up to people I didn't know and stick my chewed bubble gum in their hair.
Would sit behind the bushes with rocks and wait for the nicest car and would throw rocks at it.
Would sit on the overpass of freeways and drop rocks on cars.
