I read this because the author, Kiyohiko Azuma, wrote my favorite manga [b:Yotsuba&!, Vol. 01|511240|Yotsuba&!, Vol. 01 (Yotsuba&! #1)|Kiyohiko Azuma|http://d202m5krfqbpi5.cloudfront.net/books/1284943754s/511240.jpg|499238] At first, I was a little disappointed because I didn't think this manga was as funny or as good as Yotsuba&! But I'm glad I kept reading because I found out: the more you get to know the characters, the funnier and better the story becomes. By the fourth and final volume, I was sorry to say good-bye to these girls and their teachers. The story is really just a series of interactions told in (mostly) four-paneled strips. Hilarious doesn't describe this series because it also gives you a warm happy feeling. It's a real pick-me-up when you're feeling down. Highly recommended to fans of Yotsuba&!

Edited to add: watch the anime too! It's weirdly adorable and funny :)
