What About Classmates?

Ask her for coffee anyway. The next time you two leave class, say "Hey, you wan't to go get a cup of coffee or a hot cocolate?".

Going out for coffee isn't exactly like proposing marriage...you don't need to 'build up' to asking out for coffee. Asking someone out for coffee is the way you get to know them in the first place--you get them out of the class environment into a place where you can sit, enjoy a hot beverage, and actually talk about each other.

If she's got a boyfriend, then you still get to have a coffee with someone you like to chat with. If it turns out she hates your guts, then oh well. If she's single and you discover that she has an actual interest in you, then you're a winner.

You sit and worry about rejection, and then don't act. Get resolved to the fact that you will be rejected by people, tell yourself 'Well, that's their problem and their loss', and move on. Inaction can be worse than action and failure.

And remember, its just coffee.

Jam it back in, in the dark.
