Margaret Thatcher’s son, Mark, is being divorced by his wife Diane. In describing her first meeting with Mrs T, Diane says in a magazine interview: "I remember Mark addressed her as Prime Minister. "Prime Minister, this is Diane Burgdorf". I didn’t have to curtsey to her but it was very formal."
I wonder if Mrs T actually was PM at the time, or if the moniker had stuck as a pet name among her family?
Should I take a leaf out of this book and insist that my daughters’ friends address me as "Lady High Petrona"? Hmm, perhaps not.
