If I had a day off, but hadto stay inside because of the weather, I'd sleep in, get up, exercise a bit in my apartment (I can't stand being inactive all day, so I have a "back-up" exercise routine for the rare occasions when I can't get to the gym), then I'd shower, eat breakfast, play my clarinet for a while, and then spend the rest of the day watching movies, playing Sims, bumming around on the Internet, and just doing whatever, with no schedule in mind.
