Be open with your parents about your feelings towards this girl and then treat them like your buddies while you are out. If your parents didn't want you there and didn't want you to have a good time, they would have found a place for you to stay. Make an effort to rise above this challenge and have a good time. Make her parents jealous that they don't have a good, fun kid like you.
Treat her like an animal with positive reinforcement. When she is rude, ignore her. When she is pleasant, reward the behavior with friendliness. Posted via Mobile Device
