I know EXACTLY what you mean !
It`s one of the worst torture methods a person can be put through ! It wreaks havoc with your concentration , your mind , and your sanity !
I`ve found that the lower the IQ , the more a person will talk , which accounts for the inane drivel ! This doesn`t apply to women nearly as much as men , because women love to talk .......it`s their reason for living ! A woman can tell you her entire life`s history , from birth to the present , without even ONCE coming up for air !
Men are entirely different . A normal conversation between two men of normal intelligence lasts about 30-45 seconds ........ a phone call , about 90 seconds .......... and up to two minutes if it`s a matter of life and death . Any longer and your male friends begin to wonder about you !
Back to your co-worker ............
There are really only two solutions to your dilemma , Otis ! One is to simply pull out a .44 magnum next time he opens his mouth , and blow both his ears off ............ with one shot !
The other solution , which is slightly more legal , is to invest in a portable air-horn ! Every time he opens his mouth , you give him two or three ear-splitting blasts of the horn ! In a day or two , he`ll have learned the meaning of the phrase "silence is golden" , and you can work in peace !
