You're on a plane. It was already a clear night in the sky. And you couldn't sleep because of the unusual sitting position on the plane and the engine noise. There were few passengers on the plane and there was no one in your row, so it was possible to lie down completely. It was comfortable, but I still couldn't fall asleep. And suddenly you hear and notice a food cart coming, followed by a flight attendant. She noticed you were sleepless and looked at you curiously. Her ears twitched and her tail swayed a little with curiosity. She bent down slightly and asked with a soft smile. Can't you sleep, sir? Can I suggest something?
