Everyone wanted my emotions to be very simple. They wanted me to say, "I was poor and I was unhappy, and now I've got money and I'm really happy."

Many prefer not to exercise their imaginations at all. They choose to remain comfortably within the bounds of their own experience, never troubling to wonder how it would feel to have been born other than they are. They can refuse to hear screams or to peer inside cages; they can close their minds and hearts to any suffering that does not touch them personally; they can refuse to know. I might be tempted to envy people who can live that way, except that I do not think they have any fewer nightmares than I do. The wilfully unimaginative see more monsters. They are often more afraid.

Bad news, Harry. I've just been to see Professor McGonagall about the Firebolt. She – er, got a bit shirty with me. Told me I'd got my priorities wrong. Seemed to think I cared more about winning the Cup than I do about staying alive. Just because I told her I didn't care if it threw you off, as long as you caught the Snitch first.

By the time she had interpreted Harry's dreams at the top of her voice (all of which, even the ones that involved eating porridge, apparently foretold a gruesome and early death), he was feeling much less sympathetic toward her.
