"There has never been a spell on me before," the unicorn said. She shivered long and deep. "There has never been a world in which I was not known."
"I know exactly how you feel," Schmendrick said eagerly. The unicorn looked at him out of dark, endless eyes, and he smiled nervously and looked at his hands. "It's a rare man who is taken for what he truly is," he said. "There is much misjudgment in the world. Now I knew you for a unicorn when I first saw you, and I know that I am your friend. Yet you take me for a clown, or a clod, or a betrayer, and so must I be if you see me so. The magic on you is only magic and will vanish as soon as you are free, but the enchantment of error you put on me I must wear forever in your eyes. We are not always what we seem and hardly ever what we dream. Still I have read, or heard it sung, that unicorns when time was young, could tell the difference 'twixt the two - the false shining and the true, the lips' laugh and the heart's rue." His quiet voice lifted as the sky grew lighter, and for a moment the unicorn could not hear the bars whining, or the soft ringing of the harpy's wings.
"I think you are my friend," she said. "Will you help me?"
"If not you, no one," the magician answered. "You are my last chance."

"What is REAL?" asked the Rabbit one day, when they were lying side by side near the nursery fender, before Nana came to tidy the room. "Does it mean having things that buzz inside you and a stick-out handle?"
"Real isn't how you are made," said the Skin Horse. "It's a thing that happens to you. When a child loves you for a long, long time, not just to play with, but REALLY loves you, then you become Real."
"Does it hurt?" asked the Rabbit.
"Sometimes," said the Skin Horse, for he was always truthful. "When you are Real you don't mind being hurt."
"Does it happen all at once, like being wound up," he asked, "or bit by bit?"
"It doesn't happen all at once," said the Skin Horse. "You become. It takes a long time. That's why it doesn't happen often to people who break easily, or have sharp edges, or who have to be carefully kept. Generally, by the time you are Real, most of your hair has been loved off, and your eyes drop out and you get loose in your joints and very shabby. But these things don't matter at all, because once you are Real you can't be ugly, except to people who don't understand."
