That's something that my grandma and dad both lived by. Do the right thing, don't let your anger or hurt feelings get the best of your or you're stooping to the level of the person who wronged you. It doesn't mean you shouldn't stand up for yourself – it simply means taking a thoughtful approach in deciding if and how to do that.

A neighbor gets angry and holds decades-long grudges over even the smallest perceived slights – things I'd attribute to the other person having a bad day or not realizing how their words sounded. She always feels justified and is proud when she tells someone off. I couldn't live that way.
