Grandpa Song did not take Ahe's picture away. He pointed to the wooden snake between the sheets. “What had you drawn when you first stopped?”

“A snake,” Ahe said. “Then I thought more feet might make it faster.” He looked at the four feet. “But we weren't asked to draw the fastest animal.”

Grandpa Song nodded. “You can imagine all sorts of things. For this task, though, ask what is needed.” Ahe understood. His drawing had not needed more work; he had added something unnecessary after it was already right.
