My sister and I were the demon tag team!
When we were 12, we started smoking cigs, drinking, smoking pot and tripping on acid. I had a 19 year old boyfriend when I was 12. When we were 13, we started stealing my parents' cars and driving up to 90 miles away, with boys, while drinking. We'd do this at least once a week and didn't get caught for 2 years. I was expelled from 2 schools, my sister was expelled from 1 school.
From 13-16, every Sat night at midnight, we'd go to the movies. After my parents drove off, we'd go down the street where they sold everything to minors. We'd get wasted drunk, smoke a bunch of herb and we were guinea pigs for an acid dealer.
From 13-15 I tripped on acid at least 3 times a week. from 15-19 I did ecstasy at least 3 times a week.
My sister was a cokehead and pill popper. I've done just about every pill imaginable, mescaline, shrooms, peyote, etc (everything except crack and heroin)
I did tons of graffiti, snuck out of the house so many times I can't even keep track, I'd have boys I liked calling my parents pretending to be a female friend's dad saying I was going to spend the night (they always bought it)
The list goes on... We were terrible kids. All of the above happened before we were even 16 years old. (When I say "we" I mean my sister and I; twins)
