Which of the following might indicate that you are uninterested in what someone is saying

Avoiding eye contact and see somewhere else.

When you are uninterested in what someone is saying, it is the common way to avoid the eye contact and look somewhere else. In this way, the other person will get the clue that the person to whom he is talking is not interested in what he is saying.

This is the most reasonable behavior that a person can show if he is not interested in what someone is saying.
