Slipping memories
Two ladies have played bridge together for years, nay decades.
Naturally they have gotten to know each other pretty well. One day, during a game, one lady suddenly looks up at the other and says, “Now, dear, I know that we’ve known each other for many years, but please don’t be angry or upset by this–could you please tell me your name? I’m trying to remember, but I just can’t bring it to mind.”
The other lady glares at her for a full three minutes, and then replies, “How soon do you need to know?”
