" Share everything. Play fair. Don't hit people. Put things back where you found them. Clean up your mess. Don't take things that aren't yours. Say you're sorry when you hurt somebody. Wash your hands before you eat. Flush. Warm cookies and cold milk are good for you. Live some and think some and draw and paint and sing and dance and play and work every day some. Take a nap every afternoon. When you go out into the world, watch for traffic, hold hands and stick together.
Think of what a better world it would be if we all - the whole world - had cookies and milk about three o'clock every afternoon and then lay down with our blankets for a nap. Or if we had a basic policy in our nations to always put things back where we found them and clean up our messes. And it is still true, no matter how old you are, when you go out into the world, it is best to hold hands and stick together."

From " All I ever really needed to know I learned in Kindergarten" by Robert Fulghum.
