I read a math book once. And felt that it was better than Kathleen Hogan.
It had a strange problem.
If 5 people are visiting your home and you have food for 1. How many people should sit at a dining table?
Let’s see. Kathleen Hogan’s answer was 2, because 1 guest is your left hand and another guest is your right hand.
So she will serve 2 even if the food is for 1.
IMHO, none of the guests should be served the food because they are all starved. And giving food to 1 will irk another. One way or another, it’s an injustice.
