In "The Glass of Milk" by Manuel Rojas, when the young man is waiting outside the milk bar for the old man to leave, which word contributes most to the mood of restlessness and anger in ...
1. his imagined feelings toward the old man.
2. his intentions toward the old man.
3. his frustration in waiting for the old man.
4. his attempted purchase in the milk bar.
Your original question lacked clarity because parts were in the keywords section. I hope I have pieced it together successfully. It seems what you want to know is: Since the mood of the central scene is anger and restlessness, which words establish this mood in each of the four elements of the scene? This may be difficult since some of the elements are extremely short, but we'll take a look and see.
The translation of Rojas' story that I am using is by K. Beechmount. Since it is an imperfect English translation and since you may probably be using a different translations, individual words may be different within the text. I trust you'll be able to sort out any differences by closely reading your translation.
The first element of the scene is the young man's imagined feeling toward the old man, "the old geezer," who sits inside sipping a glass of milk and carefully reading a newspaper. Having decided he must eat even if he cannot pay for what he eats, the young man waits in front of the "dairy" (or milk bar) he has selected because it is clean and neat and empty but for this one customer.
He reached the first streets in the town and in one of those, he found a dairy. It was a little business very clean and bright, ...
In the dairy, there was only one customer. It was an old geezer wearing glasses, ...
The young man's feeling of pain and desperation might be said to grow into anger and restlessness as he walks then stands outside waiting for the "geezer" to leave. His "imagined feelings" toward the old man are that he is an enemy acting intentionally to interfere with the youth's hopes. What shows the anger and restlessness? The words would be: "fire relighting" "fifteen minutes" "became tired" and "threw the old man a few stony looks." These establish a mood of growing anger because of the pain he is being forced (unintentionally) to endure for long firey moments leading into exhaustion and resulting in restlessness and hostile impaitience: "throw stoney looks" is a figure of speech (an idiom) meaning to look at someone with anger burning in your eyes that seem as hard and unloving as rocks.
The words showing the mood of anger and restlessness in the second element, in his thoughts (intentions) of how he might act toward the old man,
He felt like going back and saying something strong that would force him to leave, rudeness or an expression that will tell him he didn’t have the right to remain an hour sitting and reading,
are: "strong" "force" "rudeness" "didn't have the right." The words showing the mood of anger and restlessness in the third element, his frustration in waiting for the old man, are: "finally" "finished" "at least interrupted." These show anger and restlessness because they all portray time in some way or another, and the young man's frustrated purpose has to do with getting into the dairy and getting food ... now, not later, not "finally."
It's much harder to maintain that the mood in the fourth element, his attempt to make a purchase in the "milk bar," is still that of anger and restlessness: he is indecisive, he regrets, he stumbles, he is afraid to look in the woman's face, he is "delighted" at what is to come, he has more regret, he has no daring, he has shame. These do not equate with a mood of anger and restlessness; the mood has changed to a mood of shame and regret.
Yet, if you must find words in this element that show a mood of anger and restlessness, you might find such words here: "figure out" "state of mind" "have to" "get up and leave" "without tasting." You might say anger and resentment were still a present mood because he was angry to be trapped in a situation where he might lose the prized food and restlessness because of the the blond woman watching him with "curiosity" who might force him away.
she would figure out his state of mind and shameful purpose and he would have to get up and leave, without tasting what he had ordered.
