I have a long history of saying inappropriate things, especially if I'm elevated in mood or very irritable (from hypomania, mania or depression). Actually, my mouth has gotten me in trouble more than pretty much any other thing in my life. I've lost friends for it, shocked plenty of people (friends and strangers), started fights and gotten in trouble for it, all kinds of things. Sometimes the stuff just flows out without me realizing it. I have been embarrassed because of what has come out of my mouth, but I must confess that after a lifetime of impulsivity, I learned to just say "Oh, well!" and let the realization/experience roll off my back. Even when I've lost friends for them. Unfortunately, apologies are not always accepted and sometimes when too many apologies have to be made, people stop taking them. I do better nowadays, but I'm not cured.
