Two friends got into an argument while walking through a forest, and one friend hit the other. The friend who was hit wrote in the sand that his best friend had hit him. Later, the friend who hit him saved him from drowning in a mud oasis. The friend who was saved then carved in a stone that his best friend had saved his life. He explained that hurts should be written in sand to be blown away by forgiveness, but good deeds should be carved in stone to last forever.
