The Mad Man on the Roof's themes could be PERCEPTION IN LIFE, SANITY and NATURE.
The story was written by Japanese playwright Kikuchi Kan in 1916.
"It is a short, funny story about a father who is concerned about his 24-year-old son, who climbs on the roof to watch the sunset. The father is concerned that his son is not entirely sane, and might hurt himself and embarrass the family.
His other son tries to convince his father that as long as his brother isn't hurting anyone, there is no harm in letting him sit on the roof and enjoy the sunset."
Thus, the moral of this story is "a madman who is able to enjoy the beauty of a sunset is far better off then the fully sane man who doesn't."
