Hippies

To the average person, a hippie is a dirty, smelly tree-hugger. People see them walking, and they get on the other side of the street to avoid them. You see them sitting on park benches and think they are homeless. But, they are truly thoughtful people. The reason they don't take showers is to conserve water, the reason they dress weird is because they make their own clothes, and the reason they have long hair is to show their non-conformity to society. In reality, hippies are the ultimate "green" people; they're saving our world one shower (or lack there of) at a time.
