Lynn's Comments: Going back to my friend with the big heart and too many animals: The hamster had one of those transparent exercise balls, which the kids found fascinating--as did the family cat. When the hamster was not inclined to run for his pleasure, the kids encouraged him by rolling the ball themselves. I remember them saying that they wished they could ride in a ball like that, and putting myself in place of the dizzy, disoriented hamster, I thought... yeah... maybe not!
