When nothing else in life is working, people under the moon would morn. Not sure who coiled it, but I believe it is a wise saying from someone wise. I lied, I made that up. That's however the truth for a typical Japanese mythology of Susano being the moon God. Perhaps it is only in myths that the moon is well appreciated.
It may seem weird in a way- being philosophical and all. That beneath a full moon under the dark sky, 3am in the morning, a boy would feed the cats in a park nearby his place. Perhaps, it occurs everywhere around the world. Idealistic moments such as this may not be of any significance to others.
