I was pretty tame as a youngster, too. Had I not been in a choir with very strict "dress code," I would probably have acted out a little more with the hair and facial piercings, etc. 9th-11th grade was the grunge phase for me. 12th grade was the hippie/granola phase, which didn't exactly wear off.

However, not being able to actively rebel did make me sneakier. For instance, my parents didn't notice for about a year that I had pierced my ears numerous times in the 8th grade.
