Using an excitable and unreliable narrator in "the tell-tale heart” allows edgar allan poe to

Explore human psychology.

Explanation:

In this case, Edgar Allan Poe want to depict a situation in which he himself do not want to be. That is to say, he is telling a story that he may have lived but the story is written from other perspective in which he is no involved. This "tool" of the language is useful because it allows to explore human nature and emotions.

i’m writing a memoir and i’ve been given the great suggestion of placing a ‘sub-narrative’ within some of the chapters – sort of, what was going on with me in the grand scheme of things.

i was wondering how to format this so that it is very obvious we are stepping out the of story.

firstly is a change in font from serif to sans workable? i also use dashes for a scene change. was thinking of using a different scene-changer too.

here’s a (shortened) example:

university – or what’s known as ‘uni’ in australia – were some of the best days of my life. where else do you get to potter around in a great location, have very little responsibility, learn lots of things, do lots of things and walk out four years later with a bonus – a degree!

with my university years i had immersed myself into community of intelligent ambitious people. generally everyone had a confidence about themselves. they knew where they were going in life and weren’t threatened by others.
