It was last week...
I've been getting together for coffee w/ a small group, and one of the guys happened to mention a very specific detail of the airport in the city where I grew up. For some reason, I got angry and disagreed.. I did admit that I left there in 1990, and that it could have changed since then... (but, he was wrong.... even today the airport doesn't have that detail)

LOL. I'm still not sure why it upset me. Or why I expressed my anger. I'd like to get better at recognizing my anger before expressing it, and dealing with it in constructive ways.
