What type of person were you in high school? How have you changed since then?

I have not graduated from high school yet, but I will be graduating in a couple of months (yay!). I was the quiet, nerdy kid with a small group of friends. During my last few months, I started talking more to my classmates and became more sociable. I have definitely become goofier compared to when I was a freshman.
