Fairies have to be one thing or the other, because being so small they unfortunately have room for one feeling only at a time.
They are, however, allowed to change, only it must be a complete change. At present she was full of jealousy of Wendy. What she said in her lovely tinkle Wendy could not of course understand, and I believe some of it was bad words, but it sounded kind, and she flew back and forward, plainly meaning "Follow me, and all will be well."”
