Maybe there really is no such thing as a dumb question, but sometimes I wonder.
I know, I know--the only dumb question is the one you don't ask. And if you don't ask, how will you ever know? But some questions may be better left un-asked. After all, as the proverb says, "Even a fool, when he holds his peace, is counted wise."
And as my dad used to tell me, "Better to remain silent and be thought a fool than to speak and remove all doubt."
Wisdom.
