When we are in school, we will subconsciously control our behavior at school and make ourselves more gregarious, more like normal people, especially in front of strangers, but in front of our parents or particularly familiar friends, we will look like sand sculptures, even adults, let alone children. So although the child doesn't know that much, he knows that basic camouflage can make them better integrate into this.
People need a proper disguise, and so do children. Because there are differences between people, it is impossible to be particularly similar to everything. There are definitely differences, but these differences must be kept within reasonable limits, so that many people with different growth environments can be together without conflicts. For example, as far as consumption concept is concerned, some people think that buying a dress from 200 yuan is quite expensive, while others think that buying a dress of 2000 yuan is normal. Nature is to disguise ourselves and seek common ground while reserving differences.
What is shown at home is the child's truest appearance, because the child's crown makes him particularly conducive to integrating into the group. If he can make friends, he will not be isolated, so that she can have a normal life at school. But at home, he doesn't have to pretend to be himself, because his parents know exactly what kind of person he is, and they see the child's truer side, which may grow up with him. It is normal for parents to think that their children are different from before, because everyone's growth is constantly changing. Many years later, he may feel that some of his original behaviors were particularly naive and embarrassed to dig up a castle.
If your child is smart at school, he will be rebellious. It may be that he has some problems in his cognition of family and personality, because the real personality is not against his parents, but that he has something he likes and will not change suddenly because of the secular vision. Children don't understand these things. When they were young, it was normal for them to have some childish behaviors. You can take pictures of him and show him when he grows up.
