The air hisses between the interstices of my teeth as I whisper this word over to myself, thinking of all the best ways one could have narrow gaps between objects. (And then a friend
points out that 'the nooks and crannies' of English muffins are 'buttery interstices.' It doesn't get much better than that.)
