The heart of a fool is in his mouth, but the mouth of a wise man is in his heart. ~Benjamin Franklin
Tina Miller, MA,CFLE stashed this in quotes
In general body parts should stay away from each other.
Feet don't belong in mouths, and mouths don't belong in hearts.
It seems I had quite a different spin on this than you did...
Heh. What was your spin?
I think that what good ole Ben was saying is that a fool says whatever comes to the top of his or her head, while the wise person tends to speak sincerely and thoughtfully from the heart.
Now I'd like to know your take on that.
