Two of us

From E.L. Doctorow's Ragtime:

When they ran their hair lay back from their broad foreheads. Her feet were small, her brown hands were small. She left imprints in the sand of a street runner, a climber of dark stairs; her track was a flight from the terrors of alleys and the terrible crash of ashcans. She had relieved herself in wooden outhouses behind the tenements. The tails of rodents had curled about her ankles. She knew how to sew with a machine and had observed dogs mating, whores taking on customers in hallways, drunks peeing through the wooden spokes of pushcart wheels. He had never gone without a meal. He had never been cold at night. He ran with his mind. He ran toward something. He was unencumbered by fear and did not know there were beings in the world less curious about it than he. He saw through things and noted the colors people produced and was never surprised by a coincidence. A blue and green planet rolled through his eyes.
