Provide the theme summaries for the following conversation: 

#Person1#: I see you've brought something to occupy your time while we wait. Good. We may be here for a long time.
#Person2#: Yes, Papa. I brought the catalog for the next college we're going to visit -- the one in New Hampshir.
#Person1#: Maybe we won't have to wait long. We've only been here fifteen minutes. I heard that the people here usually arrive around thirty minutes later than the time they set.
#Person2#: I'm not used to the way they treat time here. They wouldn't see me if we were in China. I missed the appointment because I was forty-five minutes late at Shanghai. I think if I was in the states, they might probably arrive latter than me.
#Person1#: It's just that Chinese people pay more attention to exact times. They're very punctual people. But the american may be more casual.
#Person2#: I think that if you're more than thirty minutes late, you have to apologize and explain what delayed you.
#Person1#: Our appointment with this dean is for three-fifteen. My watch says three-thirty. I'm sure we're not late. 
#Person3#: Lily? Come in. Sorry I kept you waiting. I did not expect that you would arrive such early!

Summary: 
Lily and her papa are waiting for the dean. They think that Chinese are more punctual while Americans are more casual. Though they've been waiting for a while, the dean thinks they arrive early.
