In case you were wondering what six-year-old hands would look like after they spent a half hour cracking open a bucket full of walnuts that they painstakingly had collected from their grandparent's yard, wonder no more. They look like this:
That is, they look like this after you've washed and scrubbed them, let them soak in the bathtub until they were sufficiently pruney, and let three days pass. They look a little worse the actual day of the walnut-cracking.
I have a newfound respect for walnuts. Don't mess with them. They've got staying power.
