Well since you're under 18, that limits my range of guesses, so I'll say 16. You look 16!
People generally think I'm older than I actually am. I guess I look older and/or act older. Some people have told me that I do that, and that I dress older too. All of that probably has some truth to it, so I don't disagree with them.
It used to make me feel bad that I looked older than I actually am, but now I don't really mind. It's not like they think I look 10-15 years older or anything. Just a few years older :)
You look older than eightteen to tell the truth - in a good way. I'd probably judge you at about 20. People always think I'm 18 because i skipped a grade and I've been in their classes and sports for as long as they have. They're always surprised to find that I'm sixteen:
