"The place I like to be the most is in a family situation, when there's no elephants under the rug," says Yacht-Panks. Play is how children play out roles in the world that they're eventually going to adopt: "They play mother, they play father,. They play all these different roles." The role of the father is to put up security so that play can occur - and he does this by ' fortifying the walls' But within the walls, then that's where play can take place; you have to have the walled garden in place for it to happen.
