“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.” 

Margery Williams Bianco (The Velveteen Rabbit)
