She longs for me merely because I am gone.

Just as motion inflicts excitement in a cats vision, if I had stayed dormant in her life I am certain she would have grown tiresome and walk away from me indifferent. Like a feline from a fresh kill.

These are the fetters of the human soul; the mind naturally fills in all blank spots, often creating a canvas much more appealing and wonderful than all logic and reality.
Thus, if I am to remain elusive and continue on as a fly just out of reach of her claws, my perpetual motion making her heart beat, her eyes dilate and all instincts of the hunt rise undeniably to the surface of her skin, she may just love me for all eternity.
