My “mouth occasionally leaps without warning from the resting position into unrestrained activity” sometimes too.
Made me laugh.
And yes: Let’s think before we talk.

My advice is simple: Stop talking.
Yes, I was embarrassed. I was also familiar with the situation in which I had placed myself. Ever since the fifth grade I have been aware that my mouth occasionally leaps without warning from the resting position into unrestrained activity. More than once I have been as shocked as anyone else when fully formed sentences have vaulted from my throat toward a target well before any conscious thought was acknowledged in my mind.
