How did the woman spend the last weekend?

M: Hey, Karen. Looks like you got some sun this weekend.
W: Yeah, I guess so.(5)I spent the weekend at the beach.
M: Oh, yeah. 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: So what are you doing back here already?
W:(6)Oh, I have a paper I need to work on. And I just couldn’t do any serious studying at the beach.
M: I don’t blame you. So what did you do out there? I mean besides lay out in the sun, obviously.
W: I jogged up and down the beach and I played some volleyball.(7)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: Not to mention cooler. 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.
