Mother earth swallow me!

I availed a copy of Harry Potter Book 7 last Saturday. When I was already on the 6th chapter, I realized that I haven't read book 6 yet. I'm stupified! So now I am in dire need for that copy. Can anyone lend me? If there's none, I have to depend on bulastog again(hyerbolic but almost true) so that i'll be able to save money. I don't want to ask my parents again for money. I'm shy. And considerate of course. Hehe. Sometimes I'm tempted to continue my reading but I know I wouldn't fully understand the book without reading the previous ones. And as much as possible, I don't talk about it when Riley's around because he's a serial spoiler. Hehe. I really feel so stupid right now. Urgh. I invested a lot on that book and I can't make use of it without buying another one. Tsk3.
