First of all, the world of children is different from that of adults, because they are simple, so they don't have to worry about many things when they do anything. So they are making friends. If they can play together, they will become very good friends. So they are different from adults in this respect. Because in many adult worlds, friendship means mutual use, and then few people can make good friends with their hearts. Therefore, the friendship between adults is often more difficult than that of children, because they think too much. Many people make friends with you in order to get some benefits from you.
In fact, even children feel at home and are not afraid of life. They may feel that they can play with him without being shy. So when two people are together, if they just met, they may become very good friends in less than five minutes. It is also possible that their friendship will last longer.
So this is why many people envy their children's friendship. Because children's world is really simple, some things that happen around them are easy for them to solve. But adults really collapse in an instant.
So if you have children in the future, you will also find that your children will hit it off with other children and become good friends soon. In fact, it is quite gratifying, because in this way, you don't have to worry that your child has no partners to play with.
It can only be said that the world of children is really simple. As the saying goes, it comes too fast, just like a tornado. So I think as an adult, don't worry too much about these things of children, just let nature take its course.
