The young girl, unable to see as she walks into a grocery store, asks an old man if she can be helped out.
"Yes, of course," he says. "What sort of groceries do you require?"
The man helps the young girl find what she is looking for, and she eventually leaves, grateful from all the help.
The old man smiles, helping other blind customers find their grocery items as well. He soon realizes that helping others is his true purpose in life.
He dies a few years later, having lived a life full of compassion and generosity.
