"Don't Fall" is a short story, and the author's original intention is to drive a car. In the first half, I looked disgusted with grandpa in the subway, not because of the foul language, but because the first-person narrative was jumping, and it was uncomfortable.
The emotional line of "can't fall"
The emotional line is clear, and the description of brothers' feelings makes people feel very real. From the younger brother's point of view, it is more a description of the younger brother's psychological activities. What is rare is that the first-person perspective is not chaotic.
From my brother's psychological activities, we can feel his extreme emotions. Lack of security, fear of being left behind, fear that my brother will not want him, and fear that my brother will marry my sister-in-law. His expression is slightly morbid, and he will have some negative romantic thoughts.
