This day is to respect our privacy so it asks for participants to go without using electricity or other civilized mechanical devices for just one day and night while telling stories to their children for educating them about what to do if touched between here and here, etc.
It allows for a family to prepare for power outages among other things and gives them an opportunity to have some serious talks.
On this night the colored dragons are coming out to eat the children and all electricity must be turned off while pictures or videos of shameful displays are destroyed by the metallic dragons chasing them.
