Question

Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
‘’Tis some visitor,’ I muttered, ‘tapping at my chamber door—
Only this, and nothing more.’
