How was your day?

It hurts. It really hurts.

I even coded the Monty Hall Problem in Python and it still didn't convince him when the odds came out 0.66 in favor of switching every time. He chalked it up to, "I don't know enough about programming to say whether that's right or not."

I even went through great pains to make it as simple as I could.

Did you ever consider that you had this conversation in the Matrix and your brother is really a loop program.
