“Aw, are we talking about human trafficking again? I don’t want to feel sad,” said F at the beginning of the session following the human-trafficking discussion. I was grateful to F since I wasn’t sure whether to continue that topic or move to something else. Thanks to his comment, I knew what to do.

Caucusing and the Four-Color Theorem

(January 30, 2020) Last week I made up a silly example of laws about dairy-product usage and decided today that I’m just going to run with it. “Suppose that your state is going to vote for a leader and that all citizens and candidates only care about one issue: the law that you can keep dairy products in your refrigerator…

Pet of the World  “What would happen if you got to vote…
