" They know that people need witches; they need the unofficial people who understand the difference between right and wrong, and when right is
wrong and when wrong is right. The world needs the people who work around the edges. They need the people who can deal with the little bumps and inconveniences. And little problems. After all, we are almost all human. Almost all of the time. "

― Terry Pratchett , I Shall Wear Midnight (Discworld, #38; Tiffany Aching, #4)
