M: Hey, Karen. Look like you’ve get some sun this weekend.
W: Yeah. I guess so. I spent the weekend at the beach.
M: Oh, that’s great. Where did you stay?
W: Some friends of my parents live out there, and they invited me there for as long as I want to stay.
M: Oh, that’s great. But how come you came back so soon? If I were you, I would stay there longer.
W: Oh, I hated to do it, but I had to. I’ve got a paper to work on. I just couldn’t do any serious studying at the beach, you know.
M: I don’t blame you then. So what did you do at there? I mean besides lying out in the sun, you must have other things to enjoy yourself.
W: Yeah. I jogged up and down the beach and I played some volleyball. You know I never realized how hard it is to run on sand. I couldn’t get through a whole game before I had to sit down. It’s much easier to run on wet sand near the water.
M: I think so. Did you go swimming?
W: I wanted to. But they said the water isn’t warm enough for that until a couple of months from now. So I just waded in up to my knees.
M: It all sounds so relaxing. I wish I could get away to the beach like that.
W: It looks like you could use it. Don’t tell me you spent the weekend in the library again.
M: Seems you are right. I’ve got a paper due next Monday.
