“a point is “zero-dimensional,” meaning it doesn’t actually exist. But once you have two points—two nonexistent points—you can fill in the space between with lots and lots of points, and you get a line, which has length, so it’s now one dimension, which you could argue means it does now exist. Miss Crane dotted her chalk against the board, over and over, in a straight line, demonstrating how a series of nothings could become something. (Actually, you could also argue the line still doesn’t exist, it’s just a concept, but I’d learned by then not to add caveats to everything I said. This was, after all, a love letter.) I told Jack how I leaned forward that day in class as if I stood with my toes hanging over the very precipice of enlightenment. In my naivete, I believed Miss Crane was about to explain something that explained everything. Something I felt I almost already knew, but could not articulate; it was related to infinity and God, the ocean and space, the universe and my dad.”
