At home it's just the bed or the sofa. When I'm on vacation I usually have a fave spot, though. On a family trip to Trinidad when I was younger, it was reading Les Miserables on the balcony, my feet up on the railing.
At dad and step-mommy's house it's the chairs by the front window. My dad calls it my office. A reading lamp, a plug for my computer, and views.
At my mother's place, in the summer, I like to sit at the back door. Have my breakfast toast and tea and read and watch the many cats and dogs roaming about.
Of course if it's cold...
