Pappu 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 Pappu went to the check-out 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 I haven’t seen in a long time.”
“That’s a shame..” replied Pappu, “Is there anything I can do for you?”
“Yes..” she said, “As I’m leaving, can you say ‘Good bye, mother!’? It would make me feel so much better.”
“Sure..” answered Pappu. So, when the old woman was leaving, Pappu called out, “Goodbye, Mother!”
As Pappu stepped up to the check-out counter, he saw that his total was $339.50. “How can that be?” Pappu asked, “I only purchased a few things!”
The clerk replied, “Your mother said that you would pay for her.”
