Professor Louise Mullany talks to Michael Rosen about politeness, and how it governs our lives, from the behaviour of football managers to the different ways children can embarrass us. Why, in this country at least, is it so mortifying to mistakenly assume someone is pregnant, when in other cultures it's simply thoughtful to book two seats on a plane for a larger person. Starring Michael Rosen as Spanish football manager Unai Emery, the politest man in football.
