I have 2 Harry Potter fans. We were there for the midnight release of the books and for the movies. It was our together time. It's fun watching their excitement.
Luckily we could afford it so money wasn't the issue. They usually did all their chores, because they knew it could easily be taken away. Now they live on their own and called me if I wanted to go to the midnight showing with them net month. I can't make it through the movie that late anymore, but it was nice they wanted me there.
