Mr. Koiwai was perplexed. He couldn't figure out why Yotsuba had been spinning around him for the last two minutes. "What's all this about, missy?" he asked.
"Today in school, we learned about the planets and stuff," she told him.
"I see," he said. "And I take it you're supposed to be planet Earth?"
Yotsuba nodded and jumped up and down. "That's right, dad...and that makes you the sun! They said I'm supposed to spin around you for 365 days."
Mr. Koiwai chuckled. "Try not to overdo it. If you get dizzy and stop spinning, your backside's gonna get cold."
