Two friends were walking through a desert, lost and dehydrated, they urgently needed to find water or be rescued. The heat of the sun got them agitated and they had an argument which led to one of them slapping the other. The injured friend front something in the sand and carried on.
Later on their journey they found an oasis and decided to cool down by taking a bath. The one who was injured got stuck on something and began drowning, until his friend dived down and freed him, saving his life. This time the friend wrote something on a nearby stone.
The reasons behind why he was writing things down is incredible!
