Quote from Rachel in The One with Two Parts: Part 2
Rachel: Mon, I'm sorry about last night, what I said. I don't think you're anything like your mother. Monica: Oh, that's all right. I don't think you were selfish for running out on Barry. Rachel: I'm sorry that I said that you were a cow in high school. Monica: That's okay. I was a cow. Rachel: I know, I'm just sorry I said it.
