Chandler: I don't want him to know we're here yet. I'm not ready. He won't be too happy to see me either.
Monica: Why not?
Chandler: I don't know if I've told you this, but he's kind of tried to get in contact me a lot over the last few years.
Monica: What?
Chandler: Yeah. He's made phone calls, written letters. He even came to New York, but I always said I was too busy to see him. It's all very "Cats in the Cradle." I don't want to get into it.
