You Don't Know That? by Zube (zube@stat.colostate.edu) Created: Aug 19, 2012 Updated: Aug 19, 2012 http://www.stat.colostate.edu/~zube/dontknow.txt The train was on time. A bright-eyed, middle-aged man with a knowing smirk alighted and whisked me off to a quiet corner of the station. With a practiced flair, he unpacked his trunk and proudly displayed all he had to offer. The wares, while moderately interesting, were unknown to me. I nodded, smiled and politely asked for details. He became angry. Roughly and forcefully, he stuffed everything back in his trunk. "You don't know that? My God, Man, I'm surprised you are smart enough to breathe! Good-bye." and he took his leave of me. While walking home, I considered the modest sack of wares I carried and happily remembered that each of us has a finite amount of time to walk a unique path. I mistakenly thought we were bartering.
