At what point in the day do you usually find yourself reading a book?
For me, it seems I'm most productive at night. Even if I'm free for the entire day, I can't get myself to sit down, crack open a book, and focus on the words while the sun's out. Besides, Twitter is a lot more enticing :) If I do read during the day, I don't seem to enjoy the novel as much--I'm not sure why, either! I tend to love/really like books when I read them later at night. Maybe it's because I'm usually tired by that point, and my brain isn't as nitpicky.
What about you?
