I will have a wiggle room and an elbow room in my family home.
The wiggle room will be for lighthearted play. The children will be able to enter that room whenever they want, and they will be able to stay in that room as long as they are wiggling.
The elbow room will be for more aggressive play. It is the room where my children will learn to protect themselves against surprise attacks by their elders. Starting at the age of four, my children will be expected to spend at least six hours a week in the elbow room. Upon entering the room, a blind and mute Russian attendant will supply the child with standard issue helmet, pads, and various materials with which to form barricades around themselves as well as (grossly insufficient, generally broken) weaponry with which to mount counteroffensives after their barricades have been destroyed and they have been mauled physically and emotionally by their elders.
