In the oval flowerbed a snail's shell is stained with red, blue, and yellow color for a couple of minutes as it passes under the flowers. The snail moves slightly in its shell, and then it labors over the loose, crumbled dirt. The snail appears to have a definite goal. A high-stepping green insect attempts to cross its path. It moves rapidly past the snail in the opposite direction. The snail looks over the cliffs of dirt and deep-green hollows. Flat blades of grass are like trees. Pebbles are like gray boulders. The snail must make its way through all of this. Now four human feet stand in front of the snail.
