Two large stones sit on a hill and wonder what's on the other side, as they can't move from the spot where they sit. When they ask a bird to check, the avian soon returns and tells them about buildings and cities on the other side. The thought of not being able to see those things makes the stones sad. A hundred years soon pass and when mouse comes, the stones ask him to check the other side of the hill. The rodent soon tells them that it is the same as the side the stones reside on. This make the stones feel glad that they're not missing anything, but wonder whether the mammal or the bird was right.
