Good for you. I have seen very few former servicemen (including a husband) who have tried to tame that tongue.
I do try. I think it is when I am alone that I have the hardest time doing it...around other people, I have made good strides.
But when I am by myself...well, I can still be voluble. And in some ways, I find that a bit more disturbing, because it is like that old saying:
“The true test of quality or honesty is what you do when nobody else is watching.”
So I do try. I fail, pick myself up,and start over!
