Christmas is for the dogs

We gave Eric an Eric-sized Jolly Ball, and Fin a tuggable soccer ball for Christmas. We also gave Eric a little bone and Fin a big bone. They know which toys are theirs, and each wants the other's. Fin looks like he's chewing gum with the little-bitty Jolly Ball, so I took it from him and returned it to Eric, where it is scaled appropriately. They still chew each other's bones, but, you know the old saying, bones are fungible ( http://dictionary.reference.com/search?q=fungible ).
