Raven Poem

From the classical poem "The Raven" by Edgar Allen Poe, one immediately develops a melancholy tone from reading. The fact that it is midnight, and described as dreary and bleak in December contribute to the overall sad mood.
The main character, the narrator, was sleeping and reading when the plot takes a twist. His wife had died, whom he loved named Lenore. A raven comes in, and the narrator starts asking it questions.
The raven only knew how to say nevermore. This comes back again and again to make the narrator more and more depressed.

Tell this soul with sorrow laden if, within the distant Aidenn,
It shall clasp a sainted maiden whom the angels name Lenore:
Clasp a rare and radiant maiden whom the angels name Lenore!"	95
Quoth the Raven, "Nevermore."

95 stanza, after this the narrator practically goes insane, combined with the terror of never seeing his wife again, he couldn't take it and went crazy. Even as he realizes the raven only knows this word, he asks more and more painful questions, and the raven responds with the same word.
Overall, we learn that this main character has continually fallen into distress and repeatedly hurts himself after losing his wife.
