Let reality tell him: learn to adapt to all environments. Everyone should grow up, not only physically, but also psychologically. Not only your brother, but also his parents. When I send my children to the military school, I should know that the military school is a well-disciplined school, where there will be many iron discipline constraints, and I should think that the children will not adapt. Why can't I explain to them in the first place? Leading children to go to school with a playful attitude, only to find that it is completely different from what they think, thus creating a serious gap. Parents regret when they are in a bad state. I really don't know how parents do it.

In this case, we should try our best to enlighten our children to be safe when they come, and learn to face the reality and adapt to the environment. But parents just want to regret it and let their children leave school. Can such parents teach a responsible child?

I doubt it.
