"This is the pattern?"
The rat studied the drawings with a slight frown, eyes narrowing as he took in each line. But after a moment, the tension on his face eased, and he seemed to follow along with my thinking.
"You're suggesting that the pattern is in the missing pieces in the drawings?"
"Yes. Now that the sample is bigger, you can clearly see that the thing that separates the children's drawings is the missing pieces. However, don't you also notice how the things that are missing are all the same? In the same pattern? Missing button. Missing button. Here, look at these two."
I pointed at two drawings.
"They both have missing buttons, but also missing the shoes."
"I can see it."
The rat nodded, following along with my words. But even as he followed, he couldn't help but ask questions.
