A young man was walking through a supermarket to pick up a few things when he found an old lady f          him.
“Pardon me,” she said. “I’m sorry if my looking s        at you has made you feel not comfortable. It's just that you look just l          my son, who died a few months a      .”
“I’m very sorry,” replied the young man. “Is there a         that I can do for you?”
“Yes,” she said, “As I’m leaving, would you s            ‘Goodbye, Mother!’? It would make me feel much b          .”
“ S          ,” answered the young man.
As the old woman was leaving, he called out, “Goodbye, Mother!” Then as he stepped up to the check-out, he saw that his b        was $ 127.00. “How can that be?” he asked. “I only bought a few things!”
The girl at the check-out replied, “Your mother said you'd p         for her.”
