Yes, I'm surprised by that as i thought those 2 memories quite important especially the one with Voldy meeting his uncle for the first time.
Interesting way of approaching HP, i read the first 2 in paperback and then the third when it came out and then saw the 1st movie and didn't like it so much that i boycotted seeing movie 2 but then shortly before PoA was released in the cinema - i borrowed the dvd off a friend. I enjoyed it better so have been going to the movies ever since.
In a way, i kinda feel sorry for you because you didn't get the whole experience of HP because you didn't have all the waiting for GoF, OOTP, HBP and DH. The reason i haven't mentioned the first 3 there was that they weren't as hard to wait for coz they were all out within a year and that not many people got the onto the phenomenon from the start.
