Since I first began collecting books as a teenager, I have turned over my complete library four times during household moves and given away scores of books along the way to make room for new purchases.
I wish I had a room with built-in bookcases on all four walls...leaving just enough space for a door and a window. Besides the bookcases, I'd have a comfortable reading chair, a footstool, and a side table big enough for a lamp, a stack of books, and a coffee cup. The table should have a drawer where I could keep my stash of dark chocolate.
I would spend a lot of time in a room like that.
