Have you even had to apologize for something you have said or done to someone?  Or have you not apologize for you felt you were right and they don't deserve one from you? Often times, we do not know how what we say or do, does to that person it is directed to, whether they deserve it or not.  Think about how much life would be better for you, by just accepting your wrongs and correcting them, especially when it has hurt someone.
