You just can't trust anybody, these days.

A little old lady and a younger man got in line next to each other at the supermarket to pay for their Thanksgiving groceries.

The old lady kept staring at the young man behind her, "pardon me, I'm sorry if my staring has mad you feel a little uncomfortable, but it's just that you look an awful lot like my son, who I haven't seen in a long time."

"Well that's a shame. Is there anything I can do for you?"

"Yes there is. As I'm leaving, can you say, 'goodbye, mother' to me? It would make me feel so much better."

The young man agreed. As the old lady was leaving he called out, "goodbye, mother!"

As he stepped up to the checkout counter and put his items on the conveyer belt, his total came to $127.50. "How can that be? I only purchased a couple of things!"

The clerk replied, "your mother said you'd pay for hers, too."
