Why pigs?

This morning, Hannah said to me, "Mom, I bet, to pigs, the shallow end of the pool is like the deep end and the deep end is like a pond and a pond is like a lake and a lake is like a sea and the sea is like an ocean and the ocean is like the whole world under water!"

I had to admit, she might be right about that.

I even can understand where the thinking about shallow and deep came in -- the girls had their first swimming lessons of the summer yesterday.

I don't know why she chose pigs, though. A mystery.
