Do you tend to forgive and forget or hold grudges? What is the longest you've ever stayed angry with someone? Is there anything the other person could say or do to win back your friendship and trust?
I really don't hold grudges for things done against me. It takes truly extreme work to make me mad at someone long-term. About the only person I can think of that I held anger against for like a year or more was my old boss, John Deep, and a lot of that was due to him torpedoing what had been my favorite job due to his deluded way of running his own company, which in the end cost everyone associated with him their jobs and got him and others sued, and got me subpoenaed to testify against him. And now I just mostly feel sorry for him and wonder if his family survived the mess.
I certainly don't hold grudges against people that did not deliberately and directly and personally do anything to me (as opposed to, say, people I've heard of in other areas of the world who actually hold grudges against people who did things generations before they were born).
