>I have nothing else to talk about! I don't know a thing about music, reality TV, night clubs, and other things that girls enjoy...

So study the things that girls enjoy. Read about the popular TV shows to at least be aware of the storylines and characters. Listen to random songs until you find something you can say you like. Pick up your newspaper's nightlife section and see what the well known clubs and restaurants are.

Or hang around the shojo/yaoi sections of comic shops and bookstores until you find a geek girl you can talk to.
