Increased blinking

In a normal, relaxed state, a person blinks six to eight times a minute, and closes his eyes for one tenth of a second. In a state of pressure, for example, speaking a lie, people begin to blink much more often. A frequent blinking is an unconscious attempt by the brain to block sight in cases where a person is bored, lost interest or feels superior. It can be said that the brain of such a person can no longer withstand communication with you, so the eyes close for two or three seconds to not see you. While the eyes are closed, the person removes you from his mind.
He wants to get rid of you
People who feel superior can also throw their heads back and look at you rather arrogantly. This is often the behavior of people whose superiority for some reason goes unnoticed. Such a gesture is characteristic of Western culture, in particular, representatives of the upper class of English society. If you notice a similar gesture during a conversation, it means that you did something wrong and you need to change tactics. If it seems to you that the interlocutor is too arrogant, try this technique: when he closes his eyes for the third or fourth time, quickly step aside. When your interlocutor opens his eyes, he will get the impression that you have disappeared and materialized elsewhere. This can make him mad. If your interlocutor begins to snore, then, most likely, your communication turned out to be unsuccessful.
