Friendly behaviour is very important in every relationship. I have seen that in the family where there is friendly behaviour between children and parents, then they have a different level because when there is friendly behaviour, everyone is able to share their views with each other and then they can assess what is right and wrong properly. They are able to take the right decisions. It becomes easy for people to analyse what kind of environment is there . So I am very happy that you know that friendly environment is very important , you have the knowledge because many don't.
