“Whoa! What are you doing?” I asked aghast.
I had just walked into my daughter’s room as she was working on a science project. Normally, I would have been pleased at such a sight. But this time, her project involved sand. A lot of it. And, while she had put some plastic underneath her work area, it wasn’t nearly enough. The sand was spreading all over our newly renovated floors.
