From the book: "It's only a movie," Alfred Hitchcock used to say when someone, especially himself, had a criticism about one of his films. So, a not entirely successful work of art is not such a big deal. Much worse is having to sneeze with a full mouth, for example during a state banquet: You cover your face with your hand, but you don't adequately cover your mouth, resulting in a spray of half-chewed pangasius fillet with princess potatoes flying at the face of the already somewhat irritable ambassador from Libya sitting across from you. And then, to make matters worse, you can't immediately remember how to say "sorry" in Arabic.
