Bartleby, The Scrivener
The classic novella of refusal.
"I looked at him steadfastly. His face was leanly composed; his gray eye dimly calm. Not a wrinkle of agitation rippled him. Had there been the least uneasiness, anger, impatience or impertinence in his manner; in other words, had there been any thing ordinarily human about him, doubtless I should have violently dismissed him from the premises."
