Activity night
From XFamily - Children of God
An evening during which the members of a Home are assembled for a communal activity. Such activities may include watching a recommended movie, an inspiration, stargazing, etc. Generally, the participants of these planned activites are peers, but occasionally age groups will mingle.
Activity nights were common during the years when Family Homes typically housed 50 to 200 people. More recently, with lower Home populations, each family unit might plan an activity on their own.
