It was somewhat sad to see the young man with the football. He seemed to have entered and exited through the window perhaps fifty times throughout this brief piece, which shares some similarities with "The Twelve Days of Christmas." Though it's not really a seasonal story, like that one, each character involved in the sequence repeats their actions, and the number of people participating grows incrementally. They consistently enter, perform identical actions, depart, stumble, change clothes—there’s even a scene involving intimacy—all observed by a camera that remains fixed in position, before everything suddenly goes into reverse, culminating with an elderly woman unexpectedly holding a football! Set to music reminiscent of a tango, the presentation is repetitive, but in a peculiar and captivating way.
