Thomas Mann said this quote

His games have a deeper meaning and fascination that adults can no longer fathom and require nothing more than three pebbles, or a piece of wood with a dandelion helmet, perhaps; but above all they require only the pure, strong, passionate, chaste, still-untroubled fantasy of those happy years when life still hesitates to touch us, when neither duty nor guilt dares lay a hand upon us, when we are allowed to see, hear, laugh, wonder, and dream without the world's demanding anything in return, when the impatience of those whom we want so much to love has not yet begun to torment us for evidence, some early token, that we will diligently fulfill our duties. Ah, it will not be long, and all that will rain down upon us in overwhelming, raw power, will assault us, stretch us, cramp us, drill us, corrupt us.
