Speaker 1: Okay, great! Bye. So guess who's coming to Thanksgiving dinner? 
Speaker 2: Sydney Portier? Hehheh. 
Speaker 1: I miss Rachel. No, my parents. 
Speaker 2: Oh! That's great, they haven't seen the place since I moved in! 
Speaker 1: Yeah, and y'know, if you could not mention to them that we live together, that would be great! I was thinking we would eat around four. 
Speaker 2: Why can't I tell them that we live together? 
Speaker 1: Because they don't know we're dating. Do you think we should eat in the kitchen? 
Speaker 2: Why haven't you told them?! 
Speaker 1: Um, well, I was going to, I-I-I really was. But um, then somewhere, just out of nowhere, I didn't. 
Speaker 2: Why haven't you told them?! Wouldn't they be happy?! 
Speaker 1: So! Dinner in the kitchen around four! I'll see you then. Speaker 1 is or was dating which Speaker?
Output:
Speaker 2
