No one likes having offended another person; hence everyone feels so much better if the other person doesn't show he's been offended. Nobody likes being confronted by a wounded spaniel. Remember that. It is much easier patiently - and tolerantly - to avoid the person you have injured than to approach him as a friend. You need courage for that.
