“It was on the third day, I think, of his being with me, and before any necessity had arisen for having his own writing examined, that, being much hurried to complete a small affair I had in hand, I abruptly called to Bartleby. In my haste and natural expectancy of instant compliance, I sat with my head bent over the original on my desk, and my right hand sideways, and somewhat nervously extended with the copy, so that immediately upon emerging from his retreat, Bartleby might snatch it and proceed to business without the least delay.

In this very attitude did I sit when I called to him, rapidly stating what it was I wanted him to do—namely, to examine a small paper with me. Imagine my surprise, nay, my consternation, when without moving from his privacy, Bartleby in a singularly mild, firm voice, replied, “I would prefer not to.”

I sat awhile in perfect silence, rallying my stunned faculties. Immediately it occurred to me that my ears had deceived me, or Bartleby had entirely misunderstood my meaning. I repeated my request in the clearest tone I could assume. But in quite as clear a one came the previous reply, “I would prefer not to.”

“Prefer not to,” echoed I, rising in high excitement, and crossing the room with a stride. “What do you mean? Are you moon-struck? I want you to help me compare this sheet here—take it,” and I thrust it towards him.

“I would prefer not to,” said he.
