instant replay

Working a conversation around in my mind. do you ever do this? Take a perfectly good conversation and replay it in your mind so many times, until you suddenly realize something was said that you wish you hadn't. Grrrrrrrrr. Initially, the intention is positive. I'm replaying it because something was so right about it, until I run across something so wrong. Reminds me I should listen more and talk less. Not that I necessarily run off at the mouth, but on occasion I can get carried away. So, I'm playing the thought over and over in my mind, and it doesn't take me long to realize I must let it go. But in that interim, I mentally thrash myself. Sigh, you'd think I'd learn.
