Thanks for replying, Sky. That's true...no matter how much I might think I know, I still have a lot to learn!

And thanks, I hope I can. I probably will come across them again in the future, unfortunately - I'm pretty sure one of them will be going to the same university as me, at least.
Good point...it'd be nice to make friends and not to assume they're going to let me down eventually.
Thanks again.
