Yotsuba&!, Volume 4 — Kiyohiko Azuma

*sniffle* Yotsuba thinks grown-ups are mean. Daddy plays all kinds of
neat games with Yotsuba, but he ALWAYS WINS! Even when Yotsuba TELLS him
to be paper in Rock-Paper-Scissors, he doesn't listen! Even then!
Yotsuba never, ever wants to be a big meanie grown-up, nuh-uh! But
grown-ups get to buy ice cream all by themselves, so...um...maybe it's okay
to be a grown-up sometimes?
