Did Outstanding People Take Supplementary Lessons On the Sly?

It was July 23rd on the thirteenth Sunday of the semester.

Dressed in a black robe, the tall and sturdy Lord of the Castle with sideburns unexpectedly arrived early that morning at the penthouse office of the upscale office building, which was the Lady of the Castle's office to begin with. They were going to receive the most important guest Mo Immortal Castle had had recently, so they had to extend the highest courtesy — a glass of fresh milk made from eight-hundred-year-old rhinoceros horn milk powder! Plus two lumps of crystal sugar!

Close to the appointed time, the Lady started to make the milk. This tin of eight-hundred-year-old rhinoceros horn milk powder was part of the Lord's collection. There were only two of them; one was secreted away in his place and the other was placed in the Lady's office for when they received important guests and for the Lord to drink when he came by in person.
