Water in the Desert

You are walking through the desert and you are dying of thirst and wondering if you can take another step. The sky is blanketed by the sun making it blend together with the sand. You see something shimmering in the distance. You walk towards it, and find a glass of ice cold water just sitting there in the sand. You fall to your knees giddy with joy, and you pick up the glass and start licking the condensation on the outside.
