People are more damaged than evil and more frightened than cruel. When people are cruel, thoughtless, unkind or rude - whether by omission or commission - remember they are wounded and don't let yourself be dragged down to their level. It might take a while to forgive and you may never forget, particularly when the hurt comes from those you love deeply, but their behaviour is their responsibility not yours, and your behaviour in response is not just your responsibility, it is your lesson.
