I acquired all the books soon after they became available, buying many used or otherwise discounted, and one was a gift from my niece and nephew. Of course the rest of the family had them, too, and sometimes one person's books ended up at another's house. One time I was able to identify my copy of one volume by a corner having been chewed by a puppy! Otherwise all the books were in good condition and I have them all with dust jackets. I had the DVD series up till at least the fifth, which walked off after my niece's friends visited, so I had to replace the set. I got them cheap secondhand as people sold their DVDs so they could buy extended editions or Blu-Rays.
After about the third book I had an increasingly hard time. I would read about three pages and fall asleep. They were great huge things I couldn't cram into a book holder, so had to hold myself and when I fell asleep too suddenly sometimes the books hit the floor. One time I dropped Order of the Phoenix so hard it scared my cats. It would take me most of a year to slog through one. I have a strict quota of at least twelve books to read per year and as a result would sometimes be sitting on New Year's Eve tossing down eleven Dr. Seuss books!
The first movie was so popular I thought, I'll wait till a Monday matinee weeks after its release to avoid being swarmed by germy kids. Well, I overdid it and ended up being the only one in the audience! They ran the whole film anyway, just for me! SO fun and a wonderful cherished memory! The first couple films came out before our town had a theater so I had to drive thirty miles to see them; the rest I saw here in town. My mom and uncle attended and they were both so deaf I had to sit between them to interpret!
The one which really made an impression was Order of the Phoenix. I was reading it and my teenage niece and I were joking around that my mom and sisters could see the thestrals, having been present when my grandma died, but my niece and I couldn't. She went to bed and after I woke up enough to get ready for bed, I looked in on my parents to see if everything was all right and found Mom had turned on the light as Dad was suffering chest pains. I had just time to alert my sister and he was dead in about half an hour. The next day when my niece was told she was in tears and I thought, well, she's the only one who can't see the thestrals now!
