Once we are in the midst of anger, we just can't accept our failure, instead, we point out finger on someone else's face. We just don't know how to be humble, we don't even show our self-respect, much more with other people. What a shame for not looking at ourselves and don't realize that we also contribute for the failures of others.
They said that friends can turn into foe and never enemies into friends. For me, it's not worth putting my pride first and losing a friend. What more could there be left after losing them. Our life evolves and becomes lighter because of friends and and we have to count every family member as our friends too. Much more if we can't make friendship even within our family. Maybe afterall, you can tell to yourself that you are the one who failed.
