Every time you open your mouth you let men look into your mind.

Two geese were preparing to start their journey southward for their annual migration when a frog asked if they would be willing to take him with them. The geese said "yes", but wondered how it could be done. The frog was very creative, so he produced a long but strong stalk of grass. He persuaded the two geese to hold each end while he clung to the middle by his mouth.
The unusual three-some took off and were making good progress when the men below, observing the strange sight, loudly expressed their admiration for their creativity and wondered aloud who had been clever enough to design it. When the frog heard them, his vanity got the better of him and he opened his mouth to shout "It was I!" He immediately fell to the earth and was dashed to pieces...
...Perhaps the oldest adage aboout keeping our mouth shut is, "Keep your mouth shut and people will never know just how ignorant you are. Open it and you remove all doubt."
As in most things, there are some elements of truth in these words. However, think of what we would lose if nobody talked. Wisdom will provide us the answer as to when we should talk and when we should listen.
