Answer: * “We did put Mr. Hater, poor man, to bed a little; but he got very
little rest…”
This is the sentence that best shows the fact that the work is a first-person account. The rest of the sentences describe the action from a third-person point of view, as the narrator does not participate in the scenes. However, in the second sentence, the narrator states "We... put Mr. Hater... to bed a little." The use of the pronoun "we" indicates that the narrator was involved in the action, which makes the work a first-person account.
