Sometimes the hurt was unintentional....stupid, but unintentional. Sometimes the person is not worth making up with anyway. Only the person who was hurt can decide that.
I am not one to hold grudges. I try to look at it that we all make mistakes, speak without thinking. And maybe that person had something bad going on at the time. I really do try to believe all people are good, and because of that belief I have wound up hurt many times. Life is very short, we never know how much time we have left here. I learned that through my dad's death. I would hate to have something happen to someone, and never have the chance to say "I forgive you" or "I'm sorry"....
