Ok.....here's what you do. Find something you know she likes.....tickets to a certain concert or whatever (make sure it's something you enjoy as well in case she turns you down). Then you go to her and ask her to go.....no fudging, no maybes, no "if you don't have anything better to do" baloney. Would you like to do this? I heard you were a fan (or whatever works there). Don't improvise, lose your nerve, or figure out what she's thinking......just straight up ask.

If she says yes, there you go and no backing out. If she says no, find another lucky friend to go with. That's the best you can do.

Good luck
