"If you’ve ever sat in a room with twins, immediately you’re forced to deal with this confusion. You’re afraid to call them by name because you’re afraid you’re going to get it wrong. At first being a twin is a source of power, you can switch, you can fool people—but then it becomes a vulnerability because people confuse you when you don’t want them to. The famous story of the twins who were both spanked when either one of them did something wrong because the parents wanted to make sure they got the right twin. So that would immediately make each twin totally responsible for the other one’s actions and therefore would make you want to control the other twin’s actions. It gets quite twisted and the confusion of identities becomes quite intense."
