Oh Yotsuba, you and your 4 year old ways crack me up. For the longest time I thought there were only going to be 9 volumes, but when I ran across a Japanese version of volume 10, I about fainted. 
 In this volume Yotsuba learns how to make pancakes, gets punished for lying, and is visited by her good friend Danbo the cardboard robot! 
 There's always a good laugh here and there in these stories. Yes, they are simple and childish. But, it's a simple pleasure that makes me smile. 
 When I bought this volume, I saw volume 11 in Japanese! I will have something to look forward to next year :)
