Entertaiment is the activity that a person engages in to enjoy himself and the company of others. It can take many forms, ranging from a simple play or concert to a full-scale ceremony or religious festival. Entertaining may be purely for amusement, but it can also serve as a means of educating or encouraging moral or intellectual growth. Entertainment often hits on the points that the brain was evolved to deeply understand in order to survive, such as backstabbing and murder.
