It's a new experience for Penny to see humans in the water. Strangely, there have never been people swimming when we've been to rivers, creeks and the beach. But lately we've been jumping in with her. The first time I did it, she was so shocked she just stood on the beach whining in dismay. But now she's learned that if the toy is thrown in the water, she'd better shoot off quickly or one of the humans might just get there first.
