Those of you who are familliar with Terry Pratchett will know that in his books the anthropomorphized figurehead "Death" has a house, a yard, and a garden. He also has a grandaughter (by adoption) who has inherited some of his skill set. When regular humans come to his house they see it in a scale that makes sense to them, and they think that everything is "human" sized. But Susan (death's grandaughter) sees that there are actually vast, empty voids around the edges of all the rooms becuase try as he might, Death doesn't really understand human things like dimensions.
Our sandbox is like this. When our parishoners (who own the house I live in) put up the fence, they also decided to build a sandbox. The sandbox is 10' X 10'. It is a vast and measureless void of sand. It is Dune in minature (minus, I hope, the large carnivorous worms). I placed my 19 month old toddler in it today, about a foot from the corner. He sat with his little shovel and pail and dug up all the sand around him. He put it in the bucket. When the bucket was "too full", he stopped, and asked to be removed from the sandbox. In his own little world, he had fully experienced the sandbox. In reality, he hardly left a footprint in the savannah.
