Free time? How wonderful.
I would read, or flush and ink up a few of my fountain pens and write a couple of letters, or write a journal entry, or watch that DVD I bought 6 months ago and never had the time to watch. Maybe I'd brush my dogs, take some pictures, and post them to my facebook page. I could make my friend a music CD of artists I know he likes. Wait, I know. I'd start that watercolor sketch I've been meaning to do...
But in reality, I don't have a couple hours of free time. Lucky you!
