Understand your connections to other people. In a relationship, it does not matter what the other person does. This man is your father. Your part of the relationship demands that you respect and support him and even tolerate his erratic behavior. He may be a bad father, but remember you are entitled only to a father, not to a good father.
Again if you have a brother who is unfair, do not concern yourself with his behavior, but keep your behavior in tune with nature.
No one can hurt you unless you let them. You are hurt the moment you believe you are.In all social dealings – as a father, mother, brother, friend, citizen, etc. – remember what your role is. It does not matter what the other person does.
