Forget this business of Detroiters not watching out for each other.
My life was just saved from getting squashed by a bus by not one but to of my neighbors a block down. I was running and nearing the end of the block when two people - not together - both yelled for me not to cross the street. I figured it was because one of them had a dog that was clearly a bit interested in what I was doing. But as I got within 10 feet of the intersection, I saw that a bus was hurtling down the way. (A bus that I have waited an hour for to no avail, by the way.)
They had no idea that I was planning on stopping and turning around at that very point to end my run. They thought I was about to die and they both hollered for me to stop. I count that as two lives saved.
Let's multiply this.
