No pun intended - like everything ... there is always an end to something ... be it life, be it fun, be it day time or night time for that matter. Some things we can see and feel coming to an end - others might be quite surprising. So would we act differently if we knew an end is upon us? Or would we be doing mundane stuff, like we can witness the people do in this short movie? Eating, making love and so forth.
There is a vouyer aspect to the whole thing. Especially when it comes to the love making - so if you are sensitive be aware of it. It does show everyone as human ... just being ... doing stuff the reader of this might be doing too. But where does it end? And when does it end? How and why? Well ... I'll leave that open ... and tie it with a bow (tie)
