I appreciate your sense of humor, I really do, but the next time you decide to withhold information from me, I'd be grateful if you chose something a little less embarrassing than my home telephone number. Especially when I'm leaving a message for the event coordinator at a library.
Furthermore, in the future, a little advance warning would be nice. Once the words "You can call me at home. My phone number is..." come out of one's mouth, it's well-nigh impossible to end the sentence without providing said telephone number or else looking a complete idiot.
I'm sure when you next meet up, you and your cerebral friends will have a right old chuckle about this latest prank, but let me tell you I am not amused. You have an easy life inside my head. It's roomy and you do very little work. I'm sure plenty of brains would gladly trade places with you.
So be warned.
