A wise man once said "...". In fact, most all wise men say "...". Then, one day, a wise man decided to explain why wise men always say "...". It was because you don't learn anything when you speak. All your doing is listening to your own voice, and we wonder how you don't tire of it. HOWEVER!!! When you listen... that is when you learn stuff. Luckily, people don't listen to wise men, and so this will be lost to time, and everyone will keep talking, making us wiser.
If you do happen to see this before time makes it rot, please feel free to join the listeners. It's not that hard. In fact, some silent company would be lovely.
