Today, one of my students showed me a picture he had drawn. It had a teeny tiny Alice in the lower left hand corner, and the rest of the page was white.
When I asked what he was going to do with all of the negative space, he said that he was going to color it black.
I told him that he needed to do something other than color it all black, and he argued, "But sewers are black."
"Alice didn't fall into a sewer."
"But holes go to the sewer," he said.
"But she's not a Ninja Turtle."
Curiouser and curiouser, thought the teacher, as she watched a white rabbit lift a maintenance hole cover and jump feet first into the Los Angeles sewer system.
