My favorite indulgence is when I wake up early on the weekend or a day off and can stay in bed and read for an hour or so, I don't do it very often. Usually the fact that the critters are waiting for me gets me out of bed when I sleep in.
Other than that I read a lot at work with the kids are off playing or in the afternoon when they're at school, I read at home whenever I can fit it in, often a little in the evenings or read while eating dinner.
I listen to audiobooks in the car, when I'm working in the barn or cleaning the house, and at night to go to sleep. Audio books help feed my reading habit when I don't have time to sit down and read.
