There is a man standing at a bus stop. He waits at this bus stop each day, regardless of the weather. He is waiting patiently for a bus that will not come, the bus line was discontinued many months ago. He has a cast on his leg, but it doesn’t seem to bother him. It is old looking and you suspect the break is healed, but he hasn’t gotten around to having the cast cut off. I consider for a moment at least stopping and offering him a ride. I know he will decline.  He knows the bus will not come, but he is going nowhere, and here is where you catch the bus going there.
