Entertaiment is a wide variety of things, including food, drink and games. It can be a private entertainment, like reading or watching a film; a banquet adapted for two; a celebration, such as a wedding, birthday, or religious festival; or an event intended for thousands, such as a concert or play. Entertainment often hits on themes that the human brain was evolved to react deeply to, such as social backstabbing or murders. It can also be fun and laughter.
