I have sort of a problem in that an excellent criterion for whether I'm "enjoying" fiction or not is how desperately I NEED to finish it. "Looking forward" sort of doesn't apply, because I will either a) finish it in one sitting, or b) if I am pulled away for some reason, I will twitch like a junkie until I can get back to it. Like, there's a good reason I don't read many novels during the school year, because if I like it, I will be sitting with it until it is done or until something forces me to stop, which leads to a lot of occasions where I fall asleep with the light on at four in the morning or whatever. Fanfiction is the same, and actually one of the things I appreciate about it--I can sit down with a 10,000-word story without sacrificing the rest of my day. (Chaptered fic baffles me--even aside from WIPs, which KILL me--because, why would you break it up? I can understand putting headings on different sections, but if you put them on different PAGES, it just means that I can't judge how far along I am by the scroll bar. "I'll just read a chapter" is, like, not something I have ever said in my LIFE. Though I am sure this would be different if I had kids.)

Your definition is really much more how I come at nonfiction. If I have Thinky Thoughts about fiction I enjoy, they usually come either after I've blitzkrieged through 600 pages in a night, or when I'm reading it for the second or third or eighth time. :)
