Perpetual Motion

On a sand less stepped on by many, I drew a square whose side is twice my height. I lay on my back in that square with my head tangent to its side and with my feet on the intersection of the square's diagonals. Temperature rose in the place. My body melted. My head turned into a magnet and my feet into a pivot. On each vertex of the square emerged a magnet polar with mine. They beckoned me to join them in their play. As I approached one of them, it moved away from me. The next did the same. Again I approached another, hoping that it would be different from the previous, but I failed. They were all the same! They had planned it? I thought of stopping their mischief until I felt that some mechanisms on my pivot (feet) were giving them motivation.
