Impressive karma
We all like to think that if we do a good thing, the universe will cause something good to come back to us in return. Usually, we’re talking about lending someone the bus fare home or holding the bus for a running passenger.
In this case, the deeds were a little more impressive, as was the payback. I imagine that, when doctors save the lives of babies, they wonder a little about who the child will grow up to be. Little did this doctor know that the baby would grow up to save his life.
