Chatting

Sometimes chatting could be very funny. I can tell almost every word they are going to say. Especially when the strangers wnat to chat. They always begin and end like this:

A: Hi, how are you?
B: Fine. U?
A: Good. How old are you?
B: 23.
A: Great. Are you married?
B: No.
A: Do you have a boyfriend?
B: No.
A: Good! Can you show me your picture?
B: No.
......

I don't know why they always ask the same questions. It's boring. Everytime when I meet someone like this, I don't need delete them or something, just few more "No" they will disappear. I can't understand why they can't talk about something else.
There are some great people, too. They have something really good to talk, something funny, and useful. I learn a lot from them. Nice guys. And I know how to use Google Earth this morning. That's good! Haha...
