A few days ago I noticed there were chunks of gravel all over the garage roof. Confident they had not clambered up there by themselves, I called Seth over. "Look, Seth. There are rocks all over the roof. What do you think about that?"
There was a brief deer-in-the-headlights moment as he contemplated how to explain this phenomenon. "We were playing asteroids," he began, eyes wide. "We were just trying to get them to go all the way over!"
"I see. And is it ever going to happen again?"
The blue eyes twinkled in relief. "No, Mommy!" He scampered off.
Later, I brought Skyler in and confronted him with the same fascinating rooftop panorama. There was another moment of sacred silence. "Um...Sethie did it too!"
