To: paulienhm.com From: chrispotts@dmail.com Date: December 13 Subject: Problem with lecture date Hi Paul, I recently saw the article in City Life Magazine . It was great, but I'm sorry to tell you that I think that the magazine has made a mistake. The talk I am giving was arranged for April 30, not April 20. That is the date I have written down in my planner. I wouldn'have arranged it for the 20th because I will be on vacation then If possible, can we put a notice in the magazine telling everyone about the real date?We could also put signs up around the museum. I don't want people to miss the talk. All the best, DR.
