Germ-free...

"It seemed that my life had dwindled down to a series of one-night stands in desolate places. Watch it, I said to myself, self-pity is the last refuge of little minds and aging professional hardnoses. I knew the desolation was my own. Brightness had fallen from my interior air.

"A boy and a girl in a hand-painted lavender Chevrolet coupé made me feel better, for some reason. They were sitting close, like a body with two ducktailed heads, taking alternate sips of malted milk from the same straw, germ-free with love."
--Ross Macdonald. The Doomsters, 1958.
