“The meeting in the open of two dogs, strangers to each other, is one of the most painful, thrilling, and pregnant of all conceivabale encounters; it is surrounded by an atmosphere of the last canniness, presided over by a constraint for which I have no preciser name; they simply cannot pass each other, their mutual embarrassment is frightful to behold.”
—Thomas Mann (1875–1955)
“Loving a baby is a circular business, a kind of feedback loop. The more you give the more you get and the more you get the more you feel like giving.”
—Penelope Leach (20th century)
“Coming out, all the way out, is offered more and more as the political solution to our oppression. The argument goes that, if people could see just how many of us there are, some in very important places, the negative stereotype would vanish overnight. ...It is far more realistic to suppose that, if the tenth of the population that is gay became visible tomorrow, the panic of the majority of people would inspire repressive legislation of a sort that would shock even the pessimists among us.”
