A young man was walking through a supermarket to pick up a few things when he noticed an old lady following him around. Thinking nothing of it, he ignored her and continued on. Finally he went to the checkout line, but she got in front of him.
"Pardon me," she said, "I'm sorry if my staring at you has made you feel uncomfortable. It's just that you look just like my son, who just died recently."
"I'm very sorry," replied the young man, "is there anything I can do for you?"
