They often employ techniques of narrative.

They exhibit perceptivity.
"Now why do I regret that? Why 42 years later am I still thinking about her? Unlike most of the other kids, I was actually really nice to her" (The Important of Kindness). By hearing this quote, you can tell that George Saunders was actually there in that moment. Since he is telling the story in a first person point of view, he has a better understanding of this situation which radiates credibility. The writer describes the situations that are unfolding in his video, by including many drawings of which I've mentioned before. It gives much more life to the video, than if he had just been talking and it was a blank screen. This also paves the way for strong characterization for the character Ellen. Saunders' talks about her cat-eye glasses and hair chewing habits while inserting a drawing to support his descriptions.
They offer surprising information and observations.
Saunders' surprised me in his writing because it was so informal and it feels like a friend talking to you. It's also amazing that he can recall all of these events, even though it was 42 years ago since they occurred. In the following quote the narrator includes so many small, details about Ellen by saying, "I'd still remember the way she'd look after such an insult. Eyes cast down, a little gut kick, as if having just been reminded of her place in things and she was trying as much as possible to disappear". These details make the text very authentic and interesting to the audience. I've found this video very unique and touching because it shows how vital kindness is to yourself and your peers, and hopefully a lot of people can learn from this.
