when you say you talked to him before, do you mean that you used to be good friends? Since you are a person who always says what you think, you can tell him your thoughts directly and tell him what you think is bad about him. I hope he can understand and understand you! Besides, you also said that he is rather rigid, so you should persuade him! Everyone has his own personality and temper. With the deepening of communication, he will find out more and more about the other party, and people always have advantages and disadvantages. But now most people will only judge whether the other party is good or bad from their own standpoint, or we should look at his words and deeds from the other party's point of view or have different findings! As for whether to establish friendship with him, it depends on whether you still want to be friends with him. I don't mean to continue to make friends with him, but I feel that it's meaningless to have such a hard communication. I just think that when everyone has no interest, I should say everything I have to say and what I am dissatisfied with, and I can be honest with myself. In the end, I still feel that I can't make friends again, so forget it! Don't give up the possible friendship easily when you say nothing and everyone is still angry!
