Funniest comment ever right here! My daughter is a HP nut! We homeschool and limit screentime so she only started reading the books last year. Well, she's a voracious reader so she tore through the entire series and then re-read the series 5 times in that first month. I then allowed her to watch the movies and she's only watched them each 1-2 times, yet has nearly all memorized.
The funny thing is she has no concept of nerds, popularity, etc because she hasn't experienced it, but I was the classic nerd growing up. I had two brothers so I could hold my own but it still sucked to get picked on for being smart. I was even once told (by one of the "popular boys") that I was pretty, but too smart for anyone to like me. I attended that school for 9 years-always the nerd. Well, luckily it became a good thing in high school and being a large school, there wasn't the stigma with being smart there, but I still held on to the nerd title inside.
Anyway, my daughter is the coolest kid I know. By the standards of which I was judged in school, she would be considered a nerd too, but she has loads of self confidence and I love watching her carry herself without the shyness I see in so many kids today.
Anyway, I got off topic, but tunnels under a school? Awesome!
Well, none of the girls ever told me that I was pretty but they sure wanted tuitions though :-) The fact that I was in an all boys school didn't help the matters either. By the time I came to high school things changed for the better. Who knew that nerds with mean right hooks could actually be respected!!!
I think nerd hood wasn't as much as a problem as my own anti social behavior as a kid. I loved books and use to skip classes to read fiction novels. The problem was that kids didn't really understand why I was doing it and it came to blows on more than one occasion.
Harry Potter was my main book for the longest time and thankfully I made a few friends because of it. I am not really sure how many times I have read them in all but I can understand why your daughter is going through them like chocolate :-) It was exactly the same for me. I actually read Crichton and Clancy before I read Rowling, so it was a bit of a change for me and yet I was hooked on HP from the beginning.
I am not exactly sure whats school life is like these days but its good to hear that your girl is doing well socially.
