My five year old collected rocks.
Beautiful rocks. Black ones. Flat ones. Round ones.
They caught my attention and I decided to stack them like the cool rock towers I see when I Google images of "rock towers."
The first few minutes of stacking them became harder than I thought. I'd get four or five stacked and they would tumble. I'd start again, and then... ...the tumble.

I gave him an exasperated, "Duuuuuuude!!!"
He sat down to cry knowing how hard I had worked.
After we made up and I assured him I wasn't mad, I started the stacking again.
It took me even longer to re-stack the 7 rocks, but I finally succeed and snapped the picture above.
