The fact that she also thinks it's normal to know by heart the whole film script for The Life of Brian is something that I've gotten accustomed to. Her argument is that since it's normal to live your life according to Monty Python it is also perfectly normal to have their philosophy at hand, lest memory should play a number on her, so she has the whole movie downloaded on her phone.
Her 13 year old son, who is a famous pianist in my home town, thinks it's normal to have a mother who is into quoting films. He does it too. He knows by heart the whole script for Amadeus.
My sister and her son laugh and quote, or quote and laugh. I almost can't tell which is which any more. So it's good they've both gone. I was about to feel utterly inferior in their company. On the other hand, I've noticed that it's very easy to entertain such normal people. I can only recommend looking for signs of normality in one's family.
After a drinking binge at the Carlsberg factories, we went to see a 3-D movie at the Planetarium in Copenhagen. Both my sister and I thought it normal not to ask a kid whether he would like to go, since we wanted to do this ourselves. Later at my office, where I had to pick up a number of new books that I've gotten reissued or published, my nephew gave a piano concerto number in the salon outside my door, and then he told me this: "you know, I absolutely adore you." Now, that I found very normal. But before I got to make a similar statement which would have crowned my nephew Roman style - laurels and everything - my sister intervened and asked her son, imitating Pilate - who can't pronounce the letter R - in The Life of Brian when he interrogates Brian: "are you a Woman?" - No. "Then your father was a Woman."
