Imaginary Rocks

In Amelia's quest to always "take somefin' with us", she will pick up a rock - where none exists! The first few times she did this I was amazed and checked to be sure a small rock hadn't materialized in our carpet or wherever we happened to be. Now it's pretty commonplace - and handy because I don't have to keep track of whatever it is that she has decided to leave with, nor do I have to try to convince her to leave an item that doesn't belong to us if we happen to be somewhere else.
