A lot can be done with a few hours of quiet...
Reading through a stack of library books
A creative excursion to a craft store, antique shop or thift store
Paring down one's closet
Watching what you want on TV (NASCAR qualifying in Richmond!)
Dancing and singing to your favorite songs
But I'll start with accomplishing a task that's not so easily done with a full house - giving the kitchen floors a good scrub!
