I signed up for a remote contracting service today which resulted in a morning spent taking multiple choice tests to quantitatively prove my knowledge of editing styles. By noon it was obvious that my Oxford is near perfect, but my Chicago has slipped. How, I don’t know, except that perhaps it’s similar to when I lost my ability to count in binary on my fingers when I tried to learn hex using a similar system, meshing the two and destroying both. (One of these days, I tell myself, I will get binary back, as it was a clever sort of trick, but as of yet I haven’t found reason to bother.)
