I got to thinking of my own Lego superstitions. “When I was young, if I built a house out of Lego, the house had to be all in one color. I used to play Lego with Ian Ball who lived up the street, back in Bellingham. He used to make his house out of whatever color brick he happened to grab. Can you imagine the sort of code someone like that would write?”

“I used to build with mixed colors …” said Bug.

“What do I know?” I said, pulling my foot out of it.
