Read the text "New house". Kerri has a new house. She talks about her new living situation.
Todd: Keri, I heard you have a new house.

Keri: Yes, I do.

Todd: Oh, so what's your new house like?

Keri: It's small, it's old. It's mostly wooden in the inside. It has two bedrooms and a balcony of those rooms. Downstairs, there's like a living room area and a tatami mat room, kitchen, bathroom.

Todd: Wow, so do you live in the tatami mat room?

Keri: No, there are two tatami mat rooms. There's one upstairs and there's one downstairs and I don't live in either. One we use as kind of a spare room and the other one is my roommate's bedroom.

Todd: Oh, OK. So you have a roommate?

Keri: Yes.

Todd: What's it like having a roommate?

Keri: It's good. I like living alone too but sometimes it's nice to come home and have someone there. My roommate gets home before I do and she likes to cook so often she's cooked dinner for me.

Todd: Wow, that's nice.

Keri: I know.

Todd: Well, you do all the cleaning?

Keri: Now that you mention it, I do a lot of the cleaning but not all of it.

Todd: Oh, OK. Well, what kind of things does she make you?

Keri: Last night she made curry. I think it was an Indian curry, tomato-base.

Todd: Spicy?

Keri: Yes.

Todd: Cool. Thanks a lot, Keri.
