When we reached the park, the first thing we did was teach small gray stones how to stack on top of other stones. This only took a short amount of time, maybe 10 minutes. Most people don’t know this, but small gray stones are very smart. Most people don’t try to teach them how to do anything, so they sit still, stony in the dirt. We spread a blanket on top of the grass and watched as the small gray stones formed a wall around us. When they finished, we hung a sign on the outside of our fortress that said ‘NOT DEAD INSIDE’ and kissed each stone thank you.
