Quote from Phoebe in The One Where Estelle Dies
Joey: Well, I wanna hear it, because she keeps doing it. Phoebe: Well, no, no, wait, wait, wait. All right, I gotta go. Just listen. Promise me, that you will wait a minute before you call her. Joey: Okay. Why? Phoebe: Because a promise between friends means never having to give a reason. Joey: I love that saying!
