I have two children - a boy 12, a girl 10 years old. Recently, the son begins to harass his daughter - he starts to go to the toilet when she does well, always tries to be present when his sister changes clothes, when she goes to the bath to wash, runs back and says that he will help her rub her back, although I usually do. I understand that this is a consequence of puberty, but isn’t it going too far?

What an interesting boy, he knows how to run behind.
