Dear Mary: what should I do if a fellow passenger is reading porn?

Q. On a recent short-haul flight, I had the misfortune to be seated next to a much older man who read, for the entirety of the flight, an erotic novel on his Kindle. I tried to avert my eyes but the bright screen and lewd language kept catching my eye. I was stunned into silence for the 1.5 hours I was trapped next to him. Should I have said something, and if so, what?

A. Certain bridge players complain they can see others’ cards – and no doubt they can, but they don’t have to. Equally, lewd language on a next-door Kindle can only be seen with effort but you cannot be blamed for making that effort. Most book lovers would make the effort to assess the compatibility of an adjacent passenger. Sadly you were disappointed, and of course it would be disconcerting to be physically wedged next to such a person.
