R：Hi, Nicole. Did you have a good weekend?
    N：Yes, I did. But I feel tired today.
    R：Really? Why?
    N：Well, on Saturday I cleaned the house and played tennis. Then on Sunday I hiked in the country.
    R：And I bet you studied, too.
    N：Yeah. I studied on Sunday evening. What about you?
    R：Well, I didn't clean the house and I didn't study. I stayed in bed and watched TV.
    N：That sounds like fun, but did you exercise?
    R：Sort of. I played golf on my computer !
