I'm fourteen, almost fifteen, but most people say I look thirteen. I don't really think it makes much of a difference, haha. Though one person said I could pass for a sixth grader. I once visited my middle school to pick my little brother up and realized that a lot of the students there were taller and looked older than I was. I think I look around my age, but since I live in a predominantly Asian area and Asians tend to look young for their age, maybe I really do look younger than I really am?
I have one friend who's supposed to be in a grade above me (she's born in December), and she can easily pass as a third grader!
