I'll bet a six pack you arent a day over 15, so chances are good that you being "up" on current events isnt going to swoon her in your directions.

Your best bet is the tried and true method of: Talking about her.

Ask her questions about where she is from, what movies she likes, what she likes to do for fun, books, sports, hobbies, hair, clothes, malls, shopping, driving, family, trips, vacations, her friends, her classes, her future plans.....you get the point. Simply asking questions and learning about a girl can lead to a weeks worth of conversation.

Eventually, conversation comes naturally and you can easily ramble on for days/weeks/years etc.
