A butterfly in the room of a dying man. It flaps it's wings but won't fly away. The man is very old and due to our moralistic primitiveness has to starve to death even though he begs the doctors for mercy  so he doesn't have to struggle on. Finally the butterfly is released and flies away free of the bonds of imprisonment. The old man is also now free of his cloying body.  No wonder in Chinese culture the butterly symbolises death and release.
A fire alarm sounds at home in the early morning. Just two notes. One long blast followed by one short blast. The alarm has never sounded before and there is nothing cooking. It's his signal to tell us that it's finally over. He has been released.
