Belonging to a group

I am thinking about people in team these days. Belonging to a group is important to people. We feel important and helpful. I think it feels good to belong to a group of people and know that you are very important and have your place. We humans are social beings and we like to talk to people. People like to make friends. We enjoy spending time with friends also. When we matter to someone, it makes us happy. When we spend time with people we feel we are not lonely.
