A friend of ours waited until the last minute to send Christmas cards. She knew she had 49 folks on her list. So she rushed into a store and bought a package of 50 cards without really looking at them.
Still in a big hurry, she addressed the 49 and signed them without reading the message inside.
On Christmas Day when things had quieted down somewhat, she happened to come across the one leftover card and finally read the message she had sent to 49 of her friends.
Much to her dismay, it read like this:
This card is just to say A little gift is on the way.
Suddenly she realized that 49 of her friends were expecting a gift from her.
