It’s never as important, in retrospect, as it seems at the time. You are aggravated now and your blood is up and that makes it very difficult to have perspective on what is happening. It makes it hard to forgive or even think about forgiving. Justice is usually what is at the top of your mind in times when you have been wronged.
Later on, it can be more important just to get on with y our life with the minimum disruption possible, and sometimes that means you are willing to overlook the wrongs. Making the wrongs right may take too much effort and cost you too much. Which makes you wonder if it’s really worth it.
I find that reminding myself my future self will see this differently can help me calm down. Reminding myself that my own anger and aggravation often takes as much out of me as whatever someone else did. I like to remember that my goals are different. My goal is to live a good life, and that does not mean righting all wrongs done me, or even many of them.
It’s a strategic decision. You look at your whole life, not just your pride or your immediate reputation. If you do that, local aggravations can seem smaller and easier to let go, and then you can relax and get on with life. It’s not easy, but just reminding yourself it is possible helps.
