Explain the juxtaposition in poes the telltale heart

"The Tell Tale Heart", a Gothic short story, written by Edgar Allan Poe contains many examples of juxtaposition in the story.

Explanation:

"A juxtaposition is the contrast created, in a writing piece, by placing facts of two things close to each other."

The First juxtaposition constructed by Poe in the short story can be seen in the opening paragraph where the protagonist is pictured both "nervous" and "calm" at the same time,

"True!—nervous—very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease that sharpened my senses—not destroyed—not dulled them. Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell. How, then, am I mad? Hearken! and observe how healthily—how calmly I can tell you the whole story."

The Second juxtaposition in the story can be found in the third paragraph, where the main character explains how he "thrust" his head into the old man's room then asserts that "it took him hours to enter his head into the room."

"And then, when I had made an opening sufficient for my head, I put in a dark lantern, all closed, closed, that no light shone out, and then I thrust in my head. Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly --very, very slowly, so that I might not disturb the old man's sleep. It took me an hour to place my whole head within the opening so far that I could see him as he lay upon his bed."

because each is self-sufficient.
