Which phrase from the paragraph best contributes to the purposeful tone

jessica, a teenage girl who just wants popularity, does everything to get attention. she puts her hair in a bun and steals her mom's lipstick and such. but then she takes something and it makes her inside and outside appearance  go bad.

i just came up with that in less than 60 seconds, but tweak it up if you like it.

explanation:

you didn't give a theme but i did a question like this a while ago so i hope this is what you were looking for.

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.
