Parents are mostly shy about this aspect, even embarrassed to say it, but children will come into contact with these contents through their own efforts when they reach a certain adolescence. If parents don't tell their children, it will be more difficult to tell them if they are touched or sexually harassed at school. Therefore, only by letting parents educate their children in these aspects first can children protect themselves more and dare to speak out when they encounter something.
Moreover, in real life, there are many incidents in which female friends are sexually harassed. Most of them don't know how to deal with this kind of thing, and even some girls are afraid that this phenomenon will affect their future life and work, so they just grin and bear it. Even if the other person's behavior is too much, he still accepts it calmly, and will not tell his parents and teachers, let alone his classmates, and slowly digest it in his heart. If parents don't enlighten them, then children are likely to live in this shadow all their lives.
This girl just wants to spread this knowledge to everyone. Only by making this hidden side public can all male and female friends be respected, so that girls can protect themselves and boys can know how to protect their female classmates or friends? If the school does not carry out this activity, parents can start telling their stories when their children reach puberty. If they don't think it's appropriate, they can play animated videos for their children.
