John Green said this quote
“ Everyone in this tale has a rock-solid hamartia: hers, that she is so sick; yours, that you are so well. Were she better or you sicker, then the stars would not be so terribly crossed, but it is the nature of stars to cross, and never was Shakespeare more wrong than when he had Cassius, The fault, dear Brutus, is not in our stars, but in ourselves. ”
