It's not that we can't be together, mainly because we lack a common language. Because of the age gap, sometimes we care about different things. In your experience, he doesn't understand what you think is right, and he has no feelings. He thinks it's right, and you think it's too naive and immature, thus creating a generation gap! It is also for this reason that it is very difficult to get along with the rebellious brother. But it is not impossible. You have to find what he cares about and get to know him so that you can have a common topic with him. Over time, he will trust you, confide in you and tell you the truth. You can also get close to each other by getting to know his friends, so that he can relax his guard against you and facilitate communication.

You know, you are older than him, and he feels that he can't play with you in many places, so you have to do a lot of work to get to know him and win his favor, so as to eliminate mutual misunderstandings.

Because my brother is too rebellious, I will deal with him in this way.
