a repetitive longing

I felt sad as I watched the dog on it's leash being ignored by its owner. All the while, oblivious, while she talked to her friend. The dog would look up at her lovingly and wag it's tail wildly. While the girl just continued to ignore it. She was just focused on her friend dragging it along, as they would walk then pause, caught up in their conversation. The captive dog would eventually give up and look down in sad desparation. Then the dog would again, begin to excitedly circle around while tethered on the leash and repeat the process again. And again. While being ignored.
