Go straight to one track-minded, don't beat around the bush, don't joke, be serious. Why is this?

A typical person with low emotional intelligence is a simple person who can't joke and is single-minded. Often such people will hurt people around them and have poor interpersonal relationships. So such people should learn to be cautious. Learn to put yourself in others' shoes, put yourself in others' shoes, and pay attention to the ways and means of speaking, so that people around you will like you.
