So when it comes to saying no, you can learn from people with high emotional intelligence.
Rejection is a double-edged sword. It can help you avoid doing things you don't want to do, but it can also throw cold water on your relationships.
When they refuse others, pay attention to methods and skills, even if they say "no", they will take into account the face of the other side, so that the other side will not be hurt or embarrassed, but will not intentionally hurt others' self-esteem.
Even, if you do not refuse others with false words, hurt his self-esteem, let him hold a grudge, then, when you need help, he will not only give a helping hand, and even drop the stone.
In interpersonal communication, even if you refuse, you must know how to respect each other.
You may have good intentions at the beginning, but when the lie is exposed, it will become a crack in the friendship, causing others to no longer trust you, and eventually causing the breakup of the relationship.
