In general people stick to not speaking with full mouth;is their head empty - now, that's a different story.
From Lincoln:"Better to remain silent and be thought a fool than to speak and remove all doubt.'In praise of taciturnity' Omnium- July 23,08.
Forgot to write what I learned from 'Taciturnity':"The mouth that speaks not is sweet to hear.":-X
I agree with your sentiments - silence is often golden...
Interesting thoughts Sean.Empty vessels make the most noise.:)
Myladies,in praise of taciturnity I do just say: Thank you. :)
