So I'm torn between going to a party with a particularly attractive girl, or spending a day with a friend from Middle School that I haven't seen since graduation day. He's been trying to set things up, and his birthday is approaching. He wants to hang out on May 1st, but his birthday is a few days later. However, this may be my only chance to start a relationship with this girl, since she was a friend's friend. ADVICE? WHAT SHOULD I DO?!?!
