Rocks

We're going through a rock collecting phase.

There are boxes of rocks accumulating in our house and yard

(does this sound familiar, Nana and Bevo?)

Nora has one basic classification system for the rocks:

"smooth" (see rock on left) vs. "grumbly" (see rock on right)

Also sometimes said as "crumbly" (?)

Nora is only interested in smooth rocks...
