Yotsuba&!/Heartwarming

You are required by law to grin in delight at least once per chapter.

"Dad: I don't care that you Or   Or   That doesn't matter.
 * Most heartwarming moments in the series are provoked by Yotsuba's wide-eyed gasp of astonishment at some new, mundane discovery. The crowning moment is probably at the end of volume 3, when she learns how awesome fireworks shows are.
 * Earth is best after all, right?
 * In chapter 72, Yanda starts treating Yotsuba better. A little.
 * In volume 10, Yotsuba lies about  After that happens though, he picks her up and this exchange follows:

Yotsuba: ...Even if I break another plate?

Dad: That's fine. It's your job to screw up.

Yotsuba: Even if I break your computer?

Dad: Let's... not get too carried away. But... don't lie. Okay?

Yotsuba then goes home to see her father cooking her favorite meal next to several big bouquets, and says "Heaven." DAWWW.
