I would say I'm younger, by about 2-4 years, mentally (as in attitude, not intellect), socially, and physically and always have been. However, I've always been very mature, well behaved, and responsible in my actions for my age. Thinking about it, I believe feeling younger while acting older caused me quite a few problems growing up and still gives me problems now. I definitely feel like I should still be in high school (I'm about to start my 3rd year of college). My birth certificate says I'm twenty, but I don't look or feel twenty, so why does everyone keep expecting me to think like I'm twenty!?...Sorry, personal pet peeve here. I just wish that mental/physical/social/numerical age (and all other uncontrollable traits) didn't come with a set of this-is-how-you're-supposed-to-be's that can cause you a lot of problems if you don't or can't fit the mold exactly.
