The texts call it "impulsive." Tending to act without thought. Thing is, I don't see it as not thinking. I weigh the moment for its merits. And usually do or say what I feel. It seems to be a choice. Maybe the moment it stops being a choice, that's when I should worry. (I could really use a filter.)
For now, I like some of the "impulsive" sister words better.
Care to join me in a fanciful whimsy?
At the moment, my impulse is to ditch work and go home to sleep. Give it a few more cups of coffee.
