Don't worry about the classmates. Older students are generally much nicer
to deal with the kids right out of highschool. gosh, they get on my nerve.
Luckily, I don't teach any students below juniors.

OK, won't worry myself to death.

Yeah, lucky you. They have a little more experience once they get to you?

I tend to get along with the teenage crowd anyway. It just felt weird at first.
My way of putting it... Its never to late to get a education.
