"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."
