Well Hannah if you are lame then so am I because I thought the same thing, Happy Birthdday Harry!!! I also thought Happy Birthday Neville on the 30th.
My son and I decided to celebrate Harry's (and Neville's ) birthday with a Harry Potter marathon of DVDs and then tonight seeing OotP again. It may not be the most productive way to spend a day off but we are not ready for Harry to be over!!!
Correction, as my son reminded me, it is not really over until the last 2 movies have been made.
