What did the woman do last weekend?

M: Hey, Karen, it looks like you’ ve got some sun this weekend.
W: Yeah, I guess so. 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 beside the sea and they invited me for as long as I wanted to stay.
M: So why have you been back here already?
W: Oh, I have a paper 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 lying out in the sun.
W: I ran slowly up and down the beach, and I played some volleyball. You know I never realized how hard it is to run on sands. I couldn’ t even get through a whole game before 1 had to sit down.
M: 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.
M: It all sounds nice. I wish I could get away to the beach like that.
