The name Rafe Rounder is an example of what literary device?

An aphorism is a universally accepted truth stated in a concise, to-the-point way. Aphorisms are typically witty and memorable, often becoming adages or proverbs as people repeat them over and over.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
