I've been in several situations lately that have caused me to wonder what's happened to the thickness of my skin. I used to enjoy the fight, the back and forth, the cut down to make a point.
Seems I don't care for it much anymore. I've got myself mostly convinced that I can still "take it" and that, in certain situations, I even still enjoy that kind of argument. It's more like a priority shift, perhaps not unlike skiing. I still love to ski, but I don't go both days every weekend anymore.
