It gets to me that Hermione seems to be thinking in terms of herself and Harry having a Relationship rather than focusing on what they actually are to each other-- I think she'd have better sense. Or maybe I just hope she would.

Here maybe I see (but also generalising from one example) why people like your comments but don't qutie agree with you. This is definitely what I'd expect from a 12-year old, at least in the society that I grew up in, which should be similar to Hermione's. (Come to think of it, this reminds me of my sibling at that age, although not myself.) But it's not what I would have hoped.
