This poem was one of my favourite as a kid, i found an Excerpt in a very old software called Encarta Encyclopedia, those days i didn't have access to the internet so i always wondered what the poem meant it evoked some kind of felling inside me(i can't even explain it ) and i always thought it was not complete. For me i don't think the poem really means anything i don't think a poem needs to have meaning. this poem captures a fleeting moment just like a photograph i think the intent of the writer was to create a really vivid image, and he did that superbly well.
