Speaker 1: So-so, what do you want for lunch? 
Speaker 2: Oh, I don't know. I guess we have to eat. 
Speaker 1: Yeah, I do. What's the matter? 
Speaker 2: I'm just bummed about the way I left things with Ross. I shouldn't have lied to him about having to work. He seemed so mad at me. 
Speaker 1: Eh, don't be so hard on yourself. If someone I was still in love with was getting married... 
Speaker 2: Still in love with?! 
Speaker 1: Yeah! 
Speaker 2: I'm not in love with Ross! 
Speaker 1: Oh. No. No. Good! Yeah, me neither. 
Speaker 2: Phoebe, I'm going to Ross's wedding because he is my ex-boyfriend and that would be really uncomfortable. Not because, I'm still in love with him! I mean, hey, y'know, I like Ross as much as the next guy, y'know? Clearly I have feelings for him, but feelings don't mean love! I mean, I still have loving feelings for Ross. Yeah! But, I have, I have continuing feelings of love, but that doesn't mean that-that I'm still in love with him. Y'know? I-I have sexual feelings for him, but I do love him-Ohh! Oh my God! Oh my-why didn't you tell me?!! 
Speaker 1: We thought you knew! 
Speaker 2: We?! 
Speaker 1: Yeah, we all know! We talk about it all the time! 
Speaker 2: You all know? Does Ross know? 
Speaker 1: Oh no, Ross doesn't know anything. 
Speaker 2: Oh, I can not believe you didn't tell me! 
Speaker 1: Well, because we thought you knew!! It's so obvious! God, that would be like telling Monica, "Hey, you like things clean." Ross is or was dating which Speaker?
