A young man was walking through a supermarket to pick up a few things when he noticed an old lady following him around the store. Thinking nothing of it, he ignored her and continued on with his shopping.
Finally, he went to the checkout line, but she got in front him.”Pardon me,” she said, “I’m sorry if my staring at you has made you feel uncomfortable. It’s just that you remind me of my son who just died recently.”
“I am very sorry,” replied the young man, “is there anything that I can do for you?”
“Yes,” she said, “as I am leaving, can you just say ‘Good bye Mother!’? It would make me feel much better.”
“Sure,” answered the young man. As the old woman was leaving, he called out, “Good bye, Mother!”
As he stepped up to the checkout counter, he saw that his total was $127.50!”How can that be?” he asked, “I only purchased a few things!”
“Your mother said that you would pay for her,” said the clerk.
