Poem that scaffolded with only 6 words

I came across with this poem in my Literature class...kind of amazed and impressed by the creative idea of the poet, Llyod Schwartz...I'd like to show all of you about the poem...notice how Llyod S. played with the 6 words and the punctuations to bring out the tone of the whole poem...the replication of the italic words in the poem functioned as a separation between the previous and the next ideas..... The poem is illustrated as below,
