As a teenager, I wasn't difficult. I was very easy to get along with, and affable to anyone and everyone. I played by the rules, especially when they had good intentions behind them, and was usually the one kid in the group that kept everyone else out of trouble. However, I was very much my own person, and assumed I should have the right to be because I afforded it to everyone else. If I was difficult, it was because I had a tendency to stay up all night, roam around as I saw fit (even though I was never into anything bad), and would voice my opinions as if I were an adult and an equal to those around me. I wasn't into drugs, crime, or anything of the sort really, went very far out of my way to stay out of fights unless there was no way to avoid them - at which point I did hospitalize a few kids. I wasn't especially sexually active, despite my unusual desire for romance and and a relationship. Nope, aside from being a self aware near grown up from an early age, I was actually a really good kid who lived a lot by the 'shoulds' of life.
I didn't really start being 'wild' until in my later 20s.
