Not my favourite Cleary story, but still good. You can see how schools have changed; kids no longer stand up at their desks to read or "recite", in third grade they have usually gotten past "Telling Time" into serious schoolwork. The "Mexican Fiesta" echoes the "Good Nieghbour Policy" current in the US at the time the book was published.
I went to school with a boy named Otis, and he too was the kind that liked to "stir up some excitement." My classmate Otis was dislexic before such things were really understood so he was treated as "lazy", and used the class-clown image to deflect expectations he couldn't meet. Otis Spofford will do anything for a little fun, and likes to take control of the classroom situations, such as the "bullfight dance", to place himself at the centre of the action. But it doesn't always go his way, as we find out when he decides to throw spitballs. Miss Gitler is the image of my teachers in the sixties--the older woman who's been teaching for decades, and combines her "motherly" attitude toward her students with strict discipline. She expects her students to be "cooperative" (ie obedient) and "good citizens". I remember reading this book as a kid and learning the word "comeuppance"--meaning you will get what's coming to you!
Again, there's no Mr Spofford, nor any explanation as to where he went. Did he die? Or is Mrs Valerie Todd Spofford a "grass widow" before divorce was acceptable? She certainly wasn't the typical hausfrau of the time, since she has to work giving those dance classes to the children of her betters; she's also totally disorganised, using her kid's only 2 T-shirts as paint rags, and only ironing his clothes when he's going shirtless. There's even mention of "clumps of dust on the floor." Much closer to the reality of many kids than the perfect-family stories of the time such as *glurge* Trixie Belden and Co. Cleary set out to write realistic stories, and they are, for the most part.
It had been a good forty years since the last time I read this, and I still cheered when Ellen learns to fight back against Otis' constant teasing. I was given the ridiculously useless advice "Don't react, he just does it to get a rise out of you." My mother should have known better, she raised six boys, she should have realised what stupid counsel this was (particularly when dealing with the bullying handed out by her own sons). If I had had a child, particularly a girl, I would have given her just the opposite: Make a stand, fight back, yell. Bullies may be cowards, but if you don't fight back, they will continue to hassle you. The line of least resistance leads nowhere. This I know from experience.
