Two very elderly ladies were enjoying the sunshine on a park bench. They
had been meeting at that park every sunny day for over 12 years,
chatting, and enjoying each other's friendship.
One day the younger of the two turns to the other and says, "Please
don't be angry with me, dear, but I am embarrassed, after all these
years. What is your name? I am trying to remember, but I just can't."
The older friend stares at her, looking very distressed, says nothing
for two full minutes, and finally says, "How soon do you have to know?"
