Two very elderly ladies were enjoying the sunshine on a park bench in Miami. They had been meeting in that park every sunny day, for over 12 years...chatting, and enjoying each others friendship.
One day, the younger of the two ladies, 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 2 full minutes, and finally with tearful eyes, says...
"How soon do you have to know?"
