I've been friends with this girl for ten years. She lives down the street from me and we've been best friends since we met. But we're in high school now, and she still seems to be living in elementary school. Lately she's annoying me more than anything. She's still completely obsessed with Pokemon and Disney channel. The only things she talks about are cartoons and the Jonas Brothers. I'm starting to think we have nothing in common anymore, and it's worrying me. I can't just distance myself from her, because people have done that to me before and it hurts. She doesn't see this happening. What do I do?
