The title, as well as the line "where the sidewalk stops," which appears throughout the poem, is a metaphor. It represents a place of innocence, tranquillity, and lovely things. It may be called an extended metaphor because it goes throughout the poem. The poet is saying that where the sidewalk ends, life can be beautiful. This poem is about hope. Even though the young man who writes the poem has lost his family, he still has hope that something good will happen to him. He believes there must be someone out there who cares about him even if he doesn't care about himself. This gives him strength to go on. Hope is like a flower. When it's planted, it needs water and food to grow. Without these things, it will wither away. But without light, the plant cannot produce seeds or flowers. So too, hope requires faith in order to grow. If you have no faith in anything beyond yourself, your hope will die. In conclusion, I believe that this poem is a metaphor for life. Life tends to stop where the sidewalk ends. Something good might happen someday if we have faith in ourselves and our dreams.
