You are judging one over the other by showing more respect to usually the one with more. By favouring one you are putting 'down' on the other. You trea the one you less consider, harder
in many ways ~ less respect, expect more of them or from them, scorn them. Nothing they do can be right. This problem in a family situation is one that I struggle with constantly, not favouritism, but the lack of respect or abuse a child (an adult) has towards the father of the family. I ask god's help to help me cope with the situation . I need guidance . It hurts.
