Okay, usually the gaps I can take are 2 or 3 years. If a girl is 21, then it's not bad, same with 20. Under that, I feel strange because it's still in the teens. I know once someone turns 18, then the person is legal. However, I may be attracted to her somewhat, but she is half a decade younger than me. Should I not try? I mean, she is in a class with me, and it would seem that she is fresh out of high school and I've been out of high school for over five years. What do you think?
