I've got a crush on a girl. I know she's going to be at the same event as I do on Valentine's day (at least, according to Facebook). How retarded would it be to start a conversation with her about the subject (Like "Hey, are you coming to the X event on Valentine's day?")?
When she says yes, what should I say to her to keep the conversation going?
If you can't even think of one thing to say to her how do you expect the event to go. Talk to her like you would talk to a friend.
