Hobbies? Terry loves to study Photoshop and builds 3D graphics, so one of her two jobs is her hobby too (she is also a genealogist for a website). Richard loves math and gardening when he is not being a rocket scientist. Jenny loves video games and cooking fantastic human food when she is not an intensive care trauma nurse.
Me? After I do my rounds of hunting for flying things, pouncing on Myst, getting brushed, my hobby is sleeping, of course. What better pastime could there be?
