R.j. Palacio said this quote

no, no, it's not all random, if it really was all random, the universe would abandon us completely. and the universe doesn't. it takes care of its most fragile creations in ways we can't see. like with parents who adore you blindly. and a big sister who feels guilty for being human over you. and a little gravelly-voiced kid whose friends have left him over you. and even a pink-haired girl who carries your picture in her wallet. maybe it is a lottery, but the universe makes it all even out in the end. the universe takes care of all its birds.
