(M=man, W=woman)
M: Hi, Viola. Anybody sitting here?
W: Oh, hi, Tyler. No, have a seat. Looks like the whole dorm came to have lunch today, doesn't it¹?
M: Yeah, it does; it's crowded. They must have bused some of them in! Hey, in class today I heard you said that you have a big family.
W: That's right. I've got six brothers and five sisters².
M: Wow! That is pretty big! Are you the oldest?
W: No. Actually, I'm the second oldest.
M: That's got to be a lot of work. What do your parents do?
