I posted this on my blog but I had enough positive feedback from friends that I am adding it to a more public thread. I'm writing a series of modern parables. Please feel free to critique this, add your own, or suggest other topics for parables.
The Parable of the Navigator
Alex and Pat were in a restaurant having lunch. They agreed to meet later at a park which neither of them had previously visited.
Alex started to drive across town and found the way blocked by a torrent pouring from a broken water main. The park was on the east side of town and the water was flowing down Main street. By driving north, Alex reached a cross-street that was not blocked. Thus Alex reached the park safely.
Pat set the GPS navigator to provide directions to the park. The voice directed him to cross Main street. Pat drove into the flowing water and was drowned.
The moral: Logic and observation are safer than blind faith in an out-dated guide.
