What is the author's style in Childhood by Rainer Maria Rilke?

Rilke describes emotions in this poem impressionistically. Impressionism seeks to depict scenes or characters by using concrete details to evoke subjective and sensory impressions, rather than to accurately depict an objective reality. For example, Rilke refers to the experience of the child's unbearable waiting for the school day to end as "lumpish time," and the place where he plays after school ends as "some green place." Writers who helped popularize impressionistic writing include Thomas Mann, Virginia Woolf, and James Joyce.
