It is not possible to disentangle the different emotions, the pride, humility, pity and passion, which are excited by a look of happy love or an unexpected caress.
一个洋溢幸福爱意的眼神,或一次意外的爱抚,所激起的骄傲、谦卑、怜惜与热情,实在无法一一分开。
— Robert Louis Stevenson · Virginibus Puerisque, and Other Papers · On Falling in Love —
