Dear Dr. Boli: I just visited Philadelphia for the first time in a few decades, and I found the place changed. There used to be a “gentleman’s agreement” in Philadelphia that no building would be built higher than the statue of William Penn on City Hall. Now Philadelphia is infested with skyscrapers just like everywhere else. Why did they give up on the gentleman’s agreement? —Sincerely, A Man from Camden Who Doesn’t Get Out Much.

Dear Sir: Because the last living gentleman in Philadelphia died in 1984.
