My husband Tony sometimes says to me that I underestomate my own power, and I wander whether that makes living more hazardous for me than for other people, the way it’s dangerous for those who lack the ability to feel pain. I’ve often thought that there are certain characters who can’t or want learn the lesson of life, and that they live among us as either a nuisance or a gift. What they cause can be called trouble or it can be called change – but the point is, though they may not mean to or want to, they make it happen. They’re always stirring things up and objecting and upsetting the status quo; they won’t just leave things be. They themselves are neither bad nor good – that’s the important thing about them – but they know good from bad when they see it.
