Ron and Hermione. That was probably the biggest disappointment of my literary childhood. I could never understand why she wanted to depict the brilliant, ambitious, intelligent girl settling for the guy that not only wasn’t on her level but also that regularly treated her like crap. What sort of example is that setting for girls?? Not to mention that they were all 17 at the end of the series and none of them needed to be pairing up for life at that age. 
Thankfully I have a brilliant father who read the books because I liked them and told me in no uncertain terms that Ron wasn’t good enough for Hermione, didn’t treat her with respect, and that I should never settle like she did. Gotta love my dad. 😁
I’ve just noticed this is in the television section but Harry Potter has been made into so many different types of media at this point that it fits anywhere.
