The Mouth
There was a T.V. show way back at the dawn of time called Happy Days. In this show there was a character nicknamed The Mouth. I don't have enough remembrance of the show to know why, but that was the way it was.
When looking through the few pictures from my childhood and forward, anytime I come across pictures of my Adorable Cousin we call her The Mouth. Either she always had her mouth open, or photographers were real good at timing because in pictures at least she always had her mouth open.
I have observed in the last number of years there are several types of people in the world. Some are loud mouths, some are big mouths, and some actually have something to say (but often no one pays attention to them).
The loud mouth is heard, not because they're wise. They can drown out all the competition. Saying what they will long and loud.
The big mouth will assure everyone that they know what they are saying is true. And you better believe what they believe.
Then there are those who do know a thing or two, but they come across in such a humble way, neither long nor loud, nor in a blustering fashion. You can take what they say—or not. It's no skin off of their nose, it just is what it is.
