What does it mean to look into other people's eyes when talking?

When speaking, everyone's habits are different. Some people just like to look directly at others, so what does it mean to look directly at others?

The first one is that he likes to look others in the eyes and talk to them, so that he can express his confidence, communicate with others better, know what others are thinking and what he should do.

The second kind of person, looking into your eyes, is just groping for your thoughts. Look at your face. A person's eyes and expressions can betray him, betray his own thoughts, and make himself seem to know everything in front of him.

The third kind of person, looking into your eyes and talking, is to shock you, make you agree with him, and even make you feel scared. In her direct eyes, he doesn't know what he should say or do, disturbing your thoughts, and then he can meet the needle to achieve his goal.

Of course, there are many people in the first category. Most people just want to express their confidence and communicate with others better. Nice purpose. There are not many people with heavy intentions. If you really meet someone with a heavy heart, you should be careful, because they are calculating you all the time, and your eyes can't hide your thoughts.
