We were walking down the street of an empty city in the middle of the night. The incandescent streetlamps were our only source of light. There were two mice that were constantly chasing each other through the storm drains on the sidewalk. The two of us watched this game of tag unfold until one of the mice caught the other and unexpectedly snapped the head of the other with its jaw. They were each abstractly represented with filled in problems from a workbook and we wanted to see who “won”. I heard a congratulations.
