" I have good reason to live away from my work.” “Which is?” “That there’s almost no real work. Our main job as wizards is to convince people that we’re doing important, mysterious things all the time. It’s not hard, but the downside is that when people don’t know what you do, they don’t know what you don’t do. If I flipped that sign on my door around to say in, within twenty minutes some gormless dung-sifter would be in here asking me to magically sift his dung. Even without turning over the sign, soon, I promise you, someone will come knocking just because people saw us come in. The last thing I want is people getting the impression that they can call on me day and night to magic away all of their problems. They need to know that when I’m home I’m not at work, and when I’m at work I have more important business to attend to.” “So our main job is to look busy.” “Yes, and sometimes it takes more effort than actually being busy.
