Kurt Vonnegut's short story "Report on the Barnhouse Effect'' is an example of a postmodernism literature in a way that he used it to spark some interest on self-consciousness and criticism on topics such as history, philosophy, politics and plenty others. However, he used a language that is used by everyday people and one that can relate to many in order to convey postmodernism.
The first 8 lines make the poem sound like bad news, and the word "contagious" sets the mood for the poem. The pastoral tradition celebrates the beauty of the natural world and the simple pleasure of living in the countryside. However, the first 8 lines of the poem seem to claim the exact opposite, with words like "contagious" "surge" "cold", and "waste."
