Why is the street 'eager'at dawn How does the description of the street change the in the next two stanzas and why?

In the early morning, the street is described as "eager" because it is filled with a sense of anticipation and possibility, as the world awakens and life begins anew. As the poem progresses into the next two stanzas, the street’s description shifts to reflect a more subdued or somber atmosphere, possibly indicating the weight of daily life or the passage of time. This change emphasizes the contrast between the hopeful beginnings of a day and the routine challenges that follow, capturing the complexity of urban life.
