I’m reasonably thick skinned, and often if I feel insulted I think about it awhile and decide I am wrongly interpreting whatever pissed me off. Only a couple of times I have kept getting madder and madder instead, so then I address the person who made the remark, and it’s gone pretty well each time.
Once when a boss congratulated a new president of the “activities committee” by saying now we had a real president (after I had done it the year before, and gotten a lot done). This was years ago. Couple days later I confronted him and he said he’d been thinking about how rude that was, and was going to apologize.
I guess my point is - if you are easily insulted maybe it’s you. If you are not easily insulted and get insulted you may have to communicate with the insulting party to be able to let it go.
