Virginia Woolf, from "Kew Gardens"

"Imagine six little girls sitting before their easels twenty years ago, down by the side of a lake, painting the water-lilies. And suddenly a kiss, there on the back of my neck. And my hand shook all the afternoon so that I couldn't paint. I took out my watch and marked the hour when I would allow myself to think of the kiss for five minutes only—it was so precious."
