What kind of experience is it that my cousin is scum?

There is a cousin who is a scum and didn't get into a technical school in high school. In fact, he is very clever, that is, he is very playful, doesn't like learning, and fails to guide him in time, which leads to the gradual neglect of his studies.

When my cousin was naughty in kindergarten, he was often criticized by the teacher, which led him to become silent in front of people and gradually became a poor student who was not liked by the teacher and had no good friends to study with. I am just the opposite, because I have got good grades since I was a child. Although I am lazy and playful sometimes, I usually study hard at school, and the school I am admitted to is also the focus.

My parents' education level is not very high, so I have been asked to teach my cousin more, but I was impatient and lazy when I was in primary school and junior high school. Plus, he is only two years younger than me, so he often feels psychologically unbalanced. He doesn't think he can learn such a simple question. Why doesn't he recite more? You should find someone to teach me during the exam. I don't have a brother or sister to teach me at my age. What's the use of not learning from others?

Sometimes I feel very angry when I see him playing games instead of studying and reasoning with him. Maybe because he didn't restrict the game from the beginning, he is becoming more and more addicted now. Now I feel that I have to reflect, and I often feel sorry for him. If I can be more patient, stop laughing at him and help him more, it may make his life different.

He is smart because he can recite quickly, and he can do math and physics only by reading before the exam, but he refuses to work hard on Chinese and English. If my parents and I could be more strict in his study, the situation might be different. I came across an article he wrote about his sister before. In his mind, my sister is excellent, but because of her Excellence, others often compare her with him and make fun of her. Her sister was praised a lot, but he was scolded a lot.

I always thought he was a sensitive child, but he gradually became numb in He Run for a long time. He is a very kind child. He never cared about his sister. Maybe he was envious and disappointed in himself. Maybe it's wrong for me to treat him as a child who knows nothing. I have a lot to say, and I don't know what effect it will have on his mind.
