Quote from Rachel in The One with Phoebe's Rats
Rachel: See, Gavin. You're capable of being a nice guy. Why do you give me such a hard time? Gavin: I'm not sure. Rachel: Well, Monica seems to think it's because you have feelings for me. Gavin: I do have feelings for you. Rachel: You do? Gavin: Yes. I feel that you're a little annoying. Rachel: See, why? Gavin, why? Right when I'm about to change my opinion of you, you go and you- [Gavin kisses Rachel] And you do that.
