Some authors, when they approach the end of a book, tend to slow down. They become reluctant to end it because they love the characters and don't want to say goodbye.
I fall into the other category. I tend to speed up as I approach the end of a book. I write slightly longer hours, a few more pages--I want to get to the end and see what happens. (I'm not a pure seat-of-the-pants writer--just a hybrid. I know generally what happens, but I don't know. Not exactly.) I just this past week finished a book that grew out of all control to much longer than the very generous word count I was allowed, and because I'm one of those freakish throwbacks who write first drafts in longhand, once I finished it, I still had to get it all in the computer. For the last two weeks, I've had tunnel vision.
I forgot a haircut appointment. My hair's getting so out of control, it's beginning to resemble a mullet. (I did reschedule--and I really hope I don't forget a second time.) I forgot a doctor's appointment. Even though they called me the day before to remind me. (I'm afraid I'm really going to be in trouble with them when I try to reschedule that one.) I've been so totally focused on Finishing The Stinkin' Book That Would Not End that everything else has slid right out of my mind.
Do normal people do this? I feel semi-confident that amongst other writers, I'm surely not the only one who loses all control of ordinary life at one time or other in the process. But sometimes I wonder just how the rest of the world sees us...
