Sense of humor

One thing that I noticed here in the US is the sense of humor among the people. I see many people have sense of humor, and they try to use it as they are talking to the other people. In my country, it was very rare to see someone with sense of humor. I talked to Ryan about it, and he said, "you are right. This is a part of their work ethics." I am very happy about it because I enjoy joking with people that I like.

A few days ago, I went to Natalie's office. She had sent me an email and asked me for the reply regarding my summer forms. I said to her that I came for signing the forms.
She: Why did you come here? What did I exactly ask you?
I: You asked... Hum....
She: Come here. This is my email. I asked for ...
I: I just came here to see you [smiling]. It was a long time that I didn't see you.
She: [smiling] Read this. I asked for a reply.
I: Oh, OK. It is a kind of relay; a physical reply :)

I said that, and she busted out laughing. This was just one example. I talked to a Jamaican boy today, and we also made lots of jokes while talking.
