We have a customer who comes into the store. His name is C.
He's a nice guy. A little bit older. He was in the military and suffered some wounds that affect his memory. It's not uncommon for him to call the store repeatedly and ask the same question.
Today, C came into the store and told us his wife had been in a bad car accident. The doctors didn't expect her to live. C got so upset at the hospital that the doctors told him to go away for a little while. So he came to the store, where he proceeded to buy a bunch of stuff as a distraction.
He asked me if I'd give him a ride home. I said it was fine and offered to take him to Wal-Mart to buy some dog food. He was very grateful.
C and his wife are alone. They never had kids and I don't think either of them has any living family. Their social safety net is very thin.
The whole situation is awful. I feel bad for C. While I was helping him with his errands, he kept telling me what a good person I was to help him.
It made me sort of uncomfortable because I don't think I'm a good person. Just average.
If his wife dies, I don't know how C will cope. I imagine that he'll need a lot of help to get through the bad times.
Am I an awful person if I admit that I don't want to be that person helping?
