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.
If someone invades your privacy without just case, your reasonable assertion they had no right to do so will be ignored, and you will be emotionally badgered into admitting you feel bad about their feelings being hurt.
Of course, there's no small amount of irony in asserting that Harriet was the one whose privacy was violated with cause...
Paranoia Fuel: Anyone with any kind of secret diary or notebook will tell you this is true... thinking about your Notebook falling into the wrong hands is the stuff of this and Accidental Nightmare Fuel.
Toy Ship: Although there's no romantic interaction between them, Harriet seems pretty set on marrying Sport some day.
Remember all you little 11 year olds, never anger your teacher. Or she'll use your fellow students to torment and abuse you!
When Ole Golly manages to convince Harriet to take dancing lessons by telling her that dancing is a crucial skill for spies like Mata Hari, Harriet claims that spies are also required to learn skills like languages and martial arts, but Ole Golly dismissively responds, "That's boy spies, Harriet. You're not thinking." Considering all the developments in feminism since 1963, the remark seems a bit less innocent today.
In the 1996 film adaptation, after Harriet's classmates torment her, she carves a revenge list into her desk, and her teacher makes no comment about it. Nowadays, after all of the shootings that have happened in American schools, Harriet's list probably would have gotten her into much more serious trouble.
What an Idiot: When Harriet's notebook is discovered by her classmates, they are unsurprisingly hurt by her less than flattering notes, and form a spy catchers club bent on making Harriet's life miserable. You'd Expect: Harriet would just apologize for her notes, and then maybe they would all forgive her (Sport and Janie would for sure.) Instead: She decides to get back at them all by playing harmful pranks or embarrassing them. It makes them even angrier.'''
