Two ladies of a certain age have been friends for many decades. Over the years they have shared all kinds of activities and adventures. Lately, they've been meeting a few times a week to play cards.
One day, one is shuffling the deck when she looks at the other and says, "Now don't get mad at me. I know we've been friends for a long time, but I just can't remember your name. I've thought and thought, but I can't recall it. Please tell me what your name is."
Her friend glares at her. And continues to glare at her. Minutes pass.
Finally she says, "How soon do you need to know?"
