Yotsuba & !, Volume 4 (Yotsuba & ! #22-27)

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?
