Twinge of Sadness

I always feel a twinge of sadness, of regret, when I finish reading a good book.  It's worse when it's a trilogy, or a series, especially when you've been able to read them back to back.  I finished reading the Amber Spyglass last night and I'm still feeling the effects of it this morning.
The first time I finished the story a few years ago, I was sitting on a train, surounded by people, and had to try swallowing back the tears.  When I saw the play last year, the same thing happened.  I'm sure that if they make the two more films of the trilogy, the same will happen.
I wonder how many times I have to read it, or watch it, before it will stop affecting me.  Something tells me that it won't stop. I've seen Pan's Labyrinth three times, and each time cried at the end.  A Very Long Engagement brings tears at the beginning still, even!
The strange thing is that I should be feeling extremely happy.  My girlfriend will be here tomorrow, not just to visit, but to move here.  She's decided to move to another country, just to be with me.  I should be the happiest man in the world, and deep down I am.  For the moment though, I still can't help worrying about Will and Lyra.
