She never did mean harm, but there is no doubt that people like Heather Badcock (and like my old friend Alison Wilde), are capable of doing a lot of harm because they lack - not kindness, they have kindness - but any real consideration for the way their actions may affect other people. She though always of what an action meant to her, never sparing a thought to what it might mean to somebody else.”

“The first rule of being a ninja is, 'Do no harm.' Unless you mean to do harm. Then do lots of harm.”
