In London, some schools stop kids from having a best friend. They teach kids to play together in groups. The Sun says that some schools in England have best-friend bans. Teachers say that it's not good for kids to have only one best friend. If the best friend isn't with him or her, he or she may feel sad. Best-friend bans aren't just in England. They are also in other countries.
But many people don't think it's a good idea to have the ban. They say it's better to learn that good things don't always last at a young age. Atherton is a teacher from Canada. She says friends are very important to children. Having a best friend helps a child to be happy. "Children should have more friends. Then they can enjoy playing with many other friends, not only one," Atherton says. She also says that a best friend can know all your secrets. That is to say, you can tell your best friend everything.
