Speaker 2: You mean your pink shirt? 
Speaker 1: Faded salmon color.

Speaker 1: That's my favorite shirt! Okay? I love that shirt! 
Speaker 4: Well just ask Mona to give it back! 
Speaker 1: I don't know. I mean I-I guess I could. It's just that we didn't really end things such good terms. And if I go over there I'd be ignoring the one thing she asked me to do when we broke up, jump up my own ass and die. Mona is or was dating which Speaker?
