Of course, I'm not talking about persuading him. This is the responsibility of his parents. His parents are not doing well, and you won't surpass them! Such people will get what they deserve sooner or later!
Such a person has been a spoiled master since childhood. Of course, he can't get true love, and he will suffer on the issue of love. Do not rule out the tendency to abuse or be abused.
But if you ignore him like it's none of your business, it's your fault. We should not be too tolerant or too careless. These are all catalysts for the indulgence or perversion of villains. What is the reason why he did this? He may want you to notice his existence, because you all snubbed him. There are two ways, 1. Follow your hairstyle. 2. I can't see the effect when I tolerate you (you are not without shortcomings, but will be magnified in his eyes).
What you need most is not to tell him the cause of your headache, and he won't pay attention to your idea, because it's not from his point of view. You need to see more of his goodness, and more importantly, let him realize that your concern is for his consideration! If his behavior violates your interests, it is selfish, so what do you stop him from venting? It is impossible for him to play cards according to your idea until he understands your behavior.
In fact, the most precious quality of people is understanding and tolerance!
Try to melt this unpleasantness, keep a cheerful mood and show your generosity, which is conducive to future understanding.
Although at this stage you think he is a villain and unworthy of making friends, you should learn to understand him in a good way and re-examine such a person. Prejudice can easily destroy many good qualities of people with many shortcomings. If you can see more of his goodness, you'd better make him realize that you care about him. This is not only the art of being a man, but also the promotion of personal realm. Although this is not a long-term solution, his attitude will change.
I want to repeat that everyone should consider personal interests. In other words, it's not just him who is selfish, but all those who are indifferent to you. The way you evaluate yourself is also based on your own education. I said he was considerate. This is something you can't change now. Besides being tolerant, you should do better. In addition to showing your generosity, you should also show your upbringing and show it to the villain with a real gentleman's demeanor.
Saying "thank you" and "I'm sorry", the most basic polite expressions, is not an inevitable condition for raising a superior person. You are exaggerating his shortcomings! How can you convince him without a written reason?
Reason and tolerance can best establish your personal prestige in his heart! This is a long-term solution that you can accomplish. You will not only meet such "hooligans" in your life. This method is widely used and will be used for a lifetime.
Be impeccable with a real gentleman's demeanor and set a good example for the little people in your heart! This is much more useful than pale preaching and hard fists, and will convince him orally. In particular, don't beat him, you must convince him from your heart.
So the most telling thing is not your fist, but your self-restraint and demeanor!
