(The girls have been discussing Rachel's "proposal" to Joshua)
Rachel: I feel blue.
Monica: Sweetie, I bet you anything he's gonna call you again.
Rachel: Yeah, maybe, but y'know, I don't think I even care! I don't think he's the one I'm sad about. ...I know that I said I'm totally okay with Ross getting married, but as it turns out... I don't think I'm handling it all that well...
Phoebe: Yeah, maybe...
Rachel: ...and I am just trying to figure out why?
Phoebe: Any luck?
Rachel: Well, yeah... Y'know how Ross and I have always been on again, off again, on again, off again? ...I guess I just figured that somewhere down the road... we would be on again... again.
Monica: Y'know what? I think we all did.
