These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Ramona herself, whose series is a spin-off of the Henry Huggins series. Additionally, the first book (Beezus and Ramona) was written from Beezus' perspective; Ramona simply took over the series.
First Installment Wins: Averted, Ramona and Her Mother, Ramona Quimby: Age 8 and Ramona & Her Father are very well known.
Fridge Brilliance: Strange behaviors by older characters start to make more sense when you grow up:
In Ramona Forever, Ramona is surprised that Beezus is so willing to babysit her after school instead of going to rich and popular Pamela's house. Beezus later explains that she's not speaking to Pamela because she was always asking when Mr. Quimby is going to get a real job.
In Ramona the Pest, Miss Binney gets uncharacteristically angry when Howie asks if her mother is coming to take her home when school is over. Being a young and inexperienced teacher, this was probably a sensitive subject for her. Her coworkers may have even made jokes about the subject.
In Ramona Forever, Ramona assumes that her aunt's wedding isn't going to happen when she snaps at her fiance at the rehearsal party and they get into a fight. Aunt Bea was probably under a huge amount of stress. She was finishing teaching elementary school and writing progress reports, planning a wedding, preparing to move to Alaska, selling her car, etc... All of that finally got to her and she lost it at something fairly minor. Once she got that out, her and Hobart were able to make up pretty easily. It's just too bad it happen in front of their families.
Periphery Demographic: Adults. Technically, many kids would be older than Ramona if they're reading about her in her younger years (it's not like kindergartners or first-graders will be the ones reading Ramona the Pest or Ramona the Brave!). But adults find the books charming and nostalgic.
They Wasted a Perfectly Good Plot: Ramona's father once gets accepted for a job teaching in Oregon, and the possibility of moving and what it would mean for Ramona (leaving behind her friends, her school and even Picky-Picky's grave) is brought up. However, later on in the same book, Mr. Quimby reveals that he instead took a promotion to manager at the store where he's working.
The Woobie: To some extent, Davy in the first few books. He's slow to learn, and his parents later divorce.
In Ramona the Pest, the student's have to draw a picture of their house. "Davy's house looked like a clubhouse built by some boys who had a few old boards and not enough nails. It leaned to one side in a tired sort of way."
