The bit in the restaurant. I walked home two feet in the air, feeling all funny inside. The film is not completely consistent with Virginia Woolf's book, but perfectly thematically consistent with itself. And they're both excellent and thought-provoking. Read the book, see the movie.
Happy death needs glorifying.
Everybody will die someday, and when I go, I want my death to be the most glorious, the most perfectly blissful moment of my life. In this story, postman Sawaka leads a boring, empty life devoid of friends or family, until he runs into an old school friend of his, now a yakuza. Involving a letter read by Sawaka at a rebellious moment, a missing finger, an assassin, and a dying girl, the story evolves into a comedic mess of coincidences where Sawaka ends up hunted by the police as 'the most dangerous man in Japan', while Sawaka never even notices. Instead he is being reawakened, falling in love, finding meaning in existence, making a friend, becoming truly alive. So when he is biking through the city to reach the girl in the hospital, he is perfectly happy - up to the point where he is gunned down by the police who've barricaded the road to the hospital.
