The late Son

A guy was in a supermarket when he noticed an old lady following him around. Whenever he stopped, she stopped, and she also kept staring at him. She finally overtook him just before the checkout where she turned to him and said:

"I hope I haven’t made you feel uncomfortable - it’s just that you look so much like my late son."

"Oh, that’s ok," he said.

"I know it’s silly," she continued, "but if you called out ’Goodbye, Mother’ as I leave, it would make me ever so happy." The old lady proceeded through the checkout and as she left the supermarket, the man called out "Goodbye Mother." The old lady waved back, and kindly smiled.

Pleased he had brought a bit of sunshine to someone’s day the man went to pay for his groceries.

"That’ll be 105 dollars 35," said the clerk.

"How come?" inquired the man. "I’ve only bought a few things!"

"Yeah, but your mother said you’d pay for her..."
