Turning Red
I was a passenger many years ago on a Boeing 727 (Delta Airlines I think) New York to Miami. We were cruising along when “ding” was heard through the cabin. Then “ding ding”. Then “ding ding ding ding”. Everyone looked at each other with a bit of alarm; then the air hostesses started laughing.
“Ding ding ding ding” faster and faster than nothing. Since all the air hostesses were staring at the back of the plane so did the passengers. Out came a young couple one after the other from the bathroom, where they’d been knocking boots against the assistance button without knowing it. The entire airplane burst into applause and the young lady turned the most lovely shade of deep red.
