I'm working on this. It's very hard for me to let something go without closure and it's very difficult for me to be around people who refuse to accept their responsibility for their part in the problem. I try very hard to always apologize if I am in the wrong, if I see my words or behavior harmed someone else. I can't walk away from a problem I know I caused without apologizing, so it is difficult for me to accept that others can't/won't do this. But I'm working on it.
