The best teachers I have ever had made their finest points outside of the typical every-day classroom lesson. A long time ago, my fourth grade school teacher wanted to teach us a valuable life lesson. He whispered five sentences into the ear of a student in the first row. She then whispered the sentences to the next kid and this went around and around until the very last student had the information. I recall being somewhere in the middle of this long whispering chain. Not surprisingly, the information had completely changed, and also, this being grade school, the results were very amusing.
