My friend from school was standing right infront of me and had no other option but to talk to me, and even if she still didn't recognise me, I would have taken her name anyway!! But I only saw the other girl briefly. It may not have been who I thought it was.
Age really doesn't matter ya know... The only issue, I feel, with a teenager going out with someone considerably older is that they may miss out on being a teenager. Maybe. Or maybe not. It depends on the circumstances. I can't really talk though, seeing as the oldest guy that I slept with was 30, when I was about 17. Feh.
Go with the flow! That is what I always say. Hope it works out for you
