If korbet is the author:
In this scene Korbet was probably nervous to give his crush Tabby a letter. When Korbet gave his letter to his crush Tabby, She crumpled up his paper (possibly mad at him) and called him a “lugnut”. The author used this scene to show others how he possibly got rejected.
Maybe character vs self???
The imagery that Poe uses to help you hear, see, smell, and feel the sensations of being buried alive is like I could feel myself gasping for air as he described this scene to me. I could see myself in the middle of tons of dirt, smelling the dust. I could hear the dirt getting piled on top of me.
The answer is number two I think
