"They stand you under a big knife, which drops and slices you neatly in two—exactly in the middle. Then they match half of you to another person who has likewise been sliced—and there you are, patched to someone you don't care about and haven't much interest in. If your half wants to do something, the other half is likely to want to do something different, and the funny part of it is you don't quite know which is your half and which is the other half. It's a terrible punishment, and in a country where one can't die or be killed until he has lived his six hundred years, to be patched is a great misfortune."
