What are the characteristics of people who can't communicate?

There are many such people around me. Maybe if I know that this person can't talk and communicate, maybe I won't care so much about him, and I'll just stop talking in the future.

First, I don't know. I've said too much. I'm speechless that they talk too inconsiderately about the environment. When they say what they want to say and the other person doesn't show discomfort, they always say that they don't know themselves and don't care about each other's feelings at all. I may have put up with this kind of person from the beginning, but I was embarrassed to fight you directly at the beginning, but that doesn't mean I will always put up with it.

Secondly, I have something similar to the above, but it doesn't seem to have anything to do with it, just being frank and saying whatever I want. Sometimes it's really good, and I like to communicate with people who tell the truth, because I am also very outspoken, but after a long time, you will find that when there are too many outspoken words, not many people around you will actually think of deeper topics for you to talk about Guan Yun.

In fact, there are many people around us who can't communicate, but sometimes you will find that as a person who often loves to talk to you, sometimes you can't bear to go back, but when a person thinks, you will feel that nothing has changed, which is his own business. Stick to your own point of view, don't put other people's ideas in your own thinking range, so no one can do anything, just feel free.
