I hear you just got back from Brazil. Did you enjoy yourself?
Yes, I had a wonderful time.
Really? Well, speaking of time, actually, I had a time problem here in the US. I was invited to my professor's house. He said to come at 7:00. I arrived at about 7:10 but I guess it was a little early.
Why? What did your professor say?
He didn't say anything. He was still in the shower. His wife opened the door.
So they were still getting ready? Well, Americans usually show up at a party about 20 or 30 minutes late. But you weren't too early.
