Do you know when to keep your mouth shut?

Best to keep your mouth shut and be thought a fool than to open it and remove all doubt.

Yes
but I ignore it

Yes I try but sometimes it gets the best of me

Usually, for me, it is right after I put my foot in it.

A foot? Too big for me.

yes
but you can bet I am thinking of a tactful way to say what I need to say
and if my opinion does not matter ,then I know how to leave that kind be
and since I have not worked for anyone for a long time I don't have a boss
but many times when I "have to keep my mouth shut "
its for the benefit for some one else
I don't talk behind your back
and I prefer disagreements settled before a day ends
I am not good with letting things fester
then I have trouble keeping my mouth shut

in a courtroom I take medication to keep me calm
Judges do tend to hate calling you down
cases I had to testify in ,not as defendant

so it depends on the situation I guess

No that's why it gets taped shut

Such a Kafkan question ...

..... and when not to.

Yes.
