This is a good thread. Thanks for this!

I've learned that "so-n-so" didn't make me mad or angry or frustrate me. I allowed them to make me angry. It's ok to be angry and sometimes the situation calls for it. But others don't dictate how my day or week is going to turn out. I get to decide that.
I am now able to say (in my head) that's your problem, not mine. To them, I'm a bit more tactful
