Tomorrow and the day after are the days that the guys ask the girls to homecoming!!! EEK!?

Pretty simple, really. Just sit with him and talk to him a little. Be gentle, though, and don't push too hard. Just say hi to him in the hall, ask him what he likes to do, etc. and thats really the best anyone can do. If he doesn't ask you, it's still not too late and you can coax him into asking you. The important thing to stress is don't be too foreward. Shy guys don't dig that.
