Other people are, as a rule, so immaterial to us that, when we have entrusted to any one of them the power to cause so much suffering or happiness to ourselves, that person seems at once to belong to a different universe, is surrounded with poetry, makes of our lives a vast expanse, quick with sensation, on which that person and ourselves are ever more or less in contact.

Marcel Proust, In Search of Lost Time, Swann in Love, Chapter 11
