I read a lot (fiction and nonfiction), watch netflix (I don't have cable anymore, I never use it and I can't stand the commercials), paint, draw, play video games, walk my dogs, collect toys/model kits, make jewelry. But mostly play with my dogs. ^_^
Since I work from home, I sometimes have downtime when there is no work to be done. That's when I hang out on internet forums, so I guess that counts, too.
