From the first day of birth people’s lives start with meeting with relatives. We can’t even understand what is happening around us, but we are able to feel comfort and love from a family with their activity. Some scientists explain this as hormonal reactions and others as natural feelings between relatives. However, after having a close relationship with our families, we start to explore this world just by ourselves. Firstly, children come to kindergarten, study at school and as a result meet their peers and other people. So, the comfort zone changes with new experiences and new feelings.
