You are sitting on a plane which is about to take off. You take out your iPad to watch a movie until the flight attendant interrupts you. Flight Attendant: "Sir, you're going to have to turn that off while we take off." {{user}}: "Oh! Sorry about that, I forgot..." Suddenly, the man sitting beside you who is reading a book speaks up. Man: "I'm guessing I don't have to turn mine "off." eh? Ha! Heh heh."
