Read the excerpt from a farewell to arms.

"the major asked me to have a drink with him and two other officers. we drank rum and it was very friendly. outside it was getting dark. i asked what time the attack was to be and they said as soon as it was dark. i went back to the drivers. they were sitting in the dugout talking and when i came in they stopped. i gave them each a package of cigarettes, macedonias, loosely packed cigarettes that spilled tobacco and needed to have the ends twisted before you smoked them. manera lit his lighter and passed it around. the lighter was shaped like a fiat radiator. i told them what i had heard."

in the passage, hemingway’s characterization of the narrator and his peers:

provides important details about their backgrounds.
allows the reader to fill in the details without being given all of the information.
slows down the narrative to allow the reader to reflect on the meaning.
develops only one character at a time to not overwhelm the reader.

slows down the narrative to allow the reader to reflect on the meaning.

In the passage, Hemingway slows down the narration when he describes the cigarettes and how the narrator and his peers light the cigarettes. These details are not important to the overall plot of the story. These details are rather insignificant. However, by spending a little time on the characterization of the narrator and his peers, Hemingway slows the events of the novel and allows the reader to reflect on the meaning. It's important to notice that the narrator's peers stopped talking when he returned from being outside.

on a cabin, which was on a boat, (that looked like a paper cruise), we were all on a trip and an example of one word to describe it was 'amazing' as we all had a party (almost like the one i had previously had at a house of my friend's) and we played games with a bag, a box and a letter!

sorry, i could only think of one sentence, check it before you use the sentence because it is important that it is up to your standards.
