Кукушен

A single person decides to celebrate a birthday for the first time in his life. He turns forty years old. He wants a holiday, noise and fun, but he doesn't have any friends. He invites work colleagues, classmates, a neighbor, in fact, random people, as if only external attributes are needed for the holiday. There is no miracle happening, and the only person who is not having fun at a birthday party is the birthday boy himself.
