Quote from Chandler in The One Where Monica Sings
Ross: I can't believe Rachel just moved on and didn't say anything to me. Chandler: Maybe she didn't move on. Maybe that kiss was just an impulsive, one-time birthday thing. Ross: No, a month ago, she gave her number to some guy in a bar. Chandler: Did she go out with him? Ross: No. When he called I threw the message away. Chandler: Ah, the high road.
