It was very hard to follow but I printed it and then underlined and highlighted important information
Close narrators tend to be more developed.
Every narrative has a different approach, and when a narrator develops closeness with his/her audience it can be assumed that it is a more developed narrator. This is because creating a relationship with your audience takes time, hardwork and trust. And all of these things come with real effort.
"Grass" is actually a poem that was written by Carl Sandburg. This is a poem in which he has published right after the World War I which is in the year 1918. Based on this poem, you can sense an unforgiving tone in it. Therefore, I can say that the attitude that the author expresses is "anger". Hope this answer helps.
