18 going on 45.
I use to get laughed at at home room in high school. I'd come in about 30 minutes early, sit at my desk with a copy of the Boston Globe, along with my local paper, laptop open to CNN, drinking a coffee and checking my stocks.
I can be sort of a boring person.....well to most average teenager kids I guess.

Ditto. 20 going on retired...

I'll add to that list:

Watched/es History Channel instead of MTV.

Studying Classical Civilizations as a career choice...
