On the unexpected longevity of a very strange theory.

A homeless man's wanderings and moral quandaries.

"Aimless, his wandering. The recurring theme of his life. That he would never escape. The single aspect of a pointless existence. What had he accomplished? The food in the bag would sustain him for two days more, three. Would his body retain any of it? Could he eat it without tasting his own wretchedness, the abhorrence that churned now through his body? A turn and then another, then down a street, an alleyway to hunker down in, only to leave abruptly because of a passing shadow, a rustle of paper. He felt persecuted, scared, timid and small. He felt disgust. For himself, the life that had prodded him thus. It was a thing that welled inside of him, the pit of his stomach, like a ball of thorny vine that tore and snagged on his delicate insides. Hours had passed. But hadn’t it been but a moment’s time? For him, all had changed; he had crossed the river to foreign shores and the language was one he could not recognize. He could not go back, though he longed to, and tried to look to the other side, but it had disappeared. He walked."
