This is just beautiful.
If there'll be more, my vote goes to the children's game idea. Maybe on a playground, using its equipment and watched by parents, who are totally fine with their children disassembling each other in their play, but occasionally throw in a line or two about how they shouldn't be mean to each other and maybe other children present, maybe also talking with other parents about their children through which we learn that it is common for children to disassemble themselves and each other in all kinds of games.
