I would like to go and buy the book on Friday night but I'm 29 weeks pg and have been told that I'm being silly. I will go and buy it on Saturday instead. I went to get book six at midnight and, along with all the other people waiting outside Smiths, was subjected to a lot of abuse by drunken idiots yelling 'You sad gits, Potter's gay hur hur hur' etc. Which was fun.
So, yes you are being unreasonable telling people who enjoy the books to get a life, but at the same time I suspect all of us fans know we are being rather daft about it...
