Some families have a dog. Or a cat. Or a guinea pig. We (I) can handle... hermit crabs. I think. We'll see...
I already love watching the kids with them. For instance, Sela named them Marianne and Rap (short for Rapunzel). And Linus says, "This one is Marianne, and this one is RAP!"
For now they're living in the kitchen. I'm surprised at how much I enjoy watching them - they're pretty entertaining. I thought it was a crack-up to see Marianne standing on top of the coconut shell!
