Old man on 16th Street

I saw him and knew something wasn't right. What could be more normal? This was an old man pushing a baby carrier.
All I know is that I kept looking as I was driving toward him, slowing down to check them both out, the old man and the baby, for a longer time.
When I passed them, I found out, looking in my rear view mirror what was not right.
The baby carrier was filled with a large blanket that seemed wet by the rain. There was no baby and the old man looked tired and sick. Not the happy grandfather pushing his grandson or granddaughter that he could have been. I watched as he stopped to sneeze in a large piece of dirty fabric that he just pulled out.
It was cold outside and he looked so lost.
