School is one place where most of us learn how to survive in the real world. Most of the survival skills we pick up we pick up from fellow students. It is also the place to pick up new ideas and ways of thinking. This we pick up from teachers as well as fellow students.
Hopefully at school we will discover ways of dealing with bullies. If not then school will become an unpleasant place to be. Here parents can help. My brother-in-law decided to take up martial arts. His children also took it up. The result? A way of dealing with bullies without becoming one yourself.
Sport is important. More important than I have given it credit for in the past. Team sports teach a person how to be a team member and player. Even if you are not good at sport it can prepare you for the business world where people still use words such as team and team player.
If your kids can't watch a popular television show at your place they'll watch it elsewhere. Hence it is better they watch it at home with you if you wish input into how they should regard the show.
My thoughts at any rate.
