Forgive even when others wont

Holding a grudge against someone who doesn't make you happy, or has upset or disappointed you, or pretending what they did to you or against you is fine won't make you happy.... But still, we are 'happier' in ourselves if we just forgive, that way when we hear a name, or see them pass by etc, we don't hurt inside. Or when we deal with them we don't feel angry. Forgiving is a good thing. Grudges are created from dark places and by fueling them we live with more angst inside than others. Not necessary really, by not forgiving the ones who created hurt or disappointment - we allow them to have power over our feelings. Not cool. If I forgive someone who upset me, I win by contentment.
