M:Oh,yeah,that’s great.Where did you stay?
W:Some friends of my parents’ live out there and they invited me for as long as I wanted to stay.
M:So what are you doing 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 sand.
I couldn’t even get through a whole game before I had to sit down.
M:Did you go swimming?
W:I wanted to,but they said the weather 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.
