And so it is, that although the ways of children cross with those of their elders in a hundred places daily, they never go in the same direction nor so much as lie in the same element.
因此,孩子与大人的生活道路,虽每天在无数地方交叉,却从不朝着同一方向,甚至并不处在同一个天地。
— Robert Louis Stevenson · Virginibus Puerisque, and Other Papers · Child’s Play —
