Even though many ppl wouldn't want me to claim that I've read the Deathly Hallows book, I guess it doesn't make a damn difference.
The fact of the matter is...I'm one of the few who's read the Book as of now. You might say it got released online and millions would've read it. Still compare that number to the number who're gna read the book ONLY after its released. It's miniscule.
It'll be a good story to tell to my kids. Your dad read the Final HP book even before it got released.
