Actually, I believe that in the first book he called Hogwarts home, so your probably right.

I really wish FicWad provided us a better way to distinguish chapter from chapter in the review system. I had to go through several before I found the original of this review...and then I had to read through the chapter to find the referent...in the Authors notes!
Yes, Harry considered Hogwarts his real home. Having grown up in the same kind of abuse until I was ten, I can agree fully. I never thought of my father's house as my home.
