Writing and measurement stand versus one another. Writing is all about feeling and expression. Measurement is about cold hard numbers. Yep, in this world writing people are basically the opposite of measurement people. Which side are you on?

Whenever it's you versus someone else, you wear a tie (たい). Naturally, your tie is always the opposite color of your opponent's tie. Kinda like how political rivals wear different color ties when they debate. It's pretty silly, but at least your tie makes it clear that it's you versus them.
