Two old ladies

Two elderly ladies had been friends for many decades. Over the years they had shared all kinds of activities and adventures. Lately, their activities had been limited to meeting a few times a week to play cards.

One day they were playing cards when one looked at the other and said, "Now don't get mad at me. I know we've been friends for a long time... but I just can't think of your name! I've thought and thought, but I can't remember it. Please tell me what your name is...?"

Her friend glared at her. For at least three minutes she just stared and glared at her. Finally she said, "How soon do you need to know?"
