How do relationships create community?

A good relationship is important in any situation, whether it be friends, family, mates, or a community. When you have a good relationship, you have, in my opinion, a better state of mind. Good relationships create a community by making the people in that community more concerned about what happens to it. It also makes the community more of a family instead of individuals who only care about themselves. The community also has a connection that only people in that community understands. The better the community relationship is, the better it will become. For example, I go to a high/ middle school named A.C.T. Charter School. It has about 300 kids in it and in a way it’s like a community. Now I admit sometimes the kids fight each other, but if another school or a group of people tries to mess with someone who goes here, the whole school steps in. That goes to show you that we care about each other even though we might not get along sometimes. Darvin's relationships page is a little different from what i'm talking about.
