Either OP is really old for a college freshman or he's lying about his age.
Wtf do you think? almost every person on the internet lies about their age, and if they don't, they're most likely above 16 or later teens, younger teens and younger just want to look older, I did it, and I know plenty of people on these forums that have done it.
The only time I would lie about my age is my alter-ego.
