Need some advice...about prom.

[BrianG]

I agree with your bro. Sounds like she's waiting for another hopeful, and if he doesn't ask her, she'll go with her second best (you). But before you go retracting the offer, just ask her straight out if that is what she's doing - she might have other reasons that our simple male minds simply cannot comprehend.

I take it you have other options?
