I have gone through a million incantations of wants. When I was younger, I wanted what I saw on every fifth cartoon commercial — the doll that could whirl through the air when you pulled a string, the dog stuffed with three or four or five babies (surprise!), the miniature playground that fit in a compact (hi Polly!). I wanted the honey-blessed cereals and the jiggling jellos. I wanted freedom in a shopping cart.
