Black No More by George S. Schuyler:
For a minute or so, Max stood irresolutely in the midst of the gibbering crowd of people. Unaccountably he felt at home here among these black folk. Their jests, scraps of conversation and lusty laughter all seemed like heavenly music. Momentarily he felt a disposition to stay among them, to share again their troubles which they seemed always to bear with a lightness that was yet not indifference. But then, he suddenly realized with just a tiny trace of remorse that the past was forever gone. He must seek other pastures, other pursuits, other playmates, other loves. He was white now. Even if he wished to stay among his folk, they would be either jealous or suspicious of him, as they were of most octoroons and nearly all whites. There was no other alternative than to seek his future among the Caucasians with whom he now rightlfully belonged.
