I hate it when footballers spit on the football pitch during a game. It's disgusting. I wonder why they do it?
I've no idea, but spitting is common in many countries.
Isn't impolite and unsanitary?
It's certainly unsanitary. There are many customs in other countries that may seem strange to us. For example, in Thailand, you should never touch someone on the head.
Interesting. I know that in some countries, you shouldn't blow your noise in front of other people.
I think that's a good custom. I hate it when people do that.
A common habit that I hate is chewing whit you mouth open. Luckily, adults rarely do it. Is seems that kids grow out of it.
Do you often scratch your head when you are thinking?
Yes, I do. I wonder why people do that? Oh look, I'm doing it now!
I rub my chin when I'm thinking. My mother scratches her nose.

Oh, the eyes-definitely. I really think you can tell a lot about a person's personality from their eyes.
I agree. Which part of the body do you find least attractive?
The feet! Why are people's feet so ugly?
I don't know, but according to this magazine survey, most people agree with you that the feet are the most unattractive part of the body and that eyes are the most attractive.
Really? What else does the survey say?
