M: Hey, Karen. Look like you’ve got some sun.
W: I guess so. I spent the weekend on the beach.
M: Really That sounds great. Where did you stay
W: Some friends of my parents live there. They invited me there for as long as I want to stay.
M: So why don’t you stay there for a longer time
W: Oh, I have a paper to work on. And I just couldn’t do any serious studying on the beach.
M: I don’t blame you. So what did you do out there I mean besides lying out in the sun.
W: I played some volleyball. I never realized how hard it is to run on sand. I couldn’t get through a whole game because I had to sit down. It’s much easier to run on wet sand near the water.
M: It must be cool. Did you go swimming
W: I intended to. But they said the water wasn’t warm enough for that. So I just wetted in up to my knees.
M: All sounds so relaxing.
W: How about your weekend Don’t tell me you spent it in the library again.
