To put it bluntly, people actually rely on talking, trusting and being recognized psychologically, and meeting these instincts can only be achieved by making friends (specifically, people who trust can be satisfied, and relatives who don't trust will not be satisfied, so the process of making friends is to find trust);
2. The derivative meaning of making friends is utilitarian value. In this society, friends travel all over the world, and it is difficult to move without friends. Because of the need of survival and development, people must make friends. Friends are ladders, platforms and carriers of self-worth.
Making friends is a way of life and exists objectively. Maybe some people don't need anything, or they don't need anything for a while, but their behavior of making friends will never stop, because making friends has become a way of their life and is inseparable from their life.
I hope it helps you.
