Captivity of perfection
Their world is perfect. They created it, carefully selecting the exhibits. They are beautiful and perfect themselves and they are surrounded by beautiful and perfect things. And today they understand that as a result they got a museum. They spent so much effort. Everything is reconciled to a micron. This is why the third chair remains empty. They look into the night - a time of love and passion, but none of them risk to offer another such an unaccounted pastime. They are too perfect for this.

And only the cat looks condescendingly at the viewer. She definitely knows the taste of real life.
