Unicorn : I am a little afraid to go home. I have been mortal, and some part of me is mortal yet. I am no longer like the others, for no unicorn was ever born who could regret, but I now I do. I regret.
Schmendrick : I am sorry. I have done you evil and I cannot undo it.
Unicorn : No. Unicorns are in the world again. No sorrow will live in me with that joy-save one. And I thank you for that part, too. Farewell good magician. I will try to go home.
–The Last Unicorn, Peter Beagle
