As much as I well and truly enjoy 'treeware', I love audio books. Not only are they enjoyable, they can make doing mundane tasks much easier. Un-son, Robin's mom found out this yesterday when I was working in the front garden. If I hadn't caught a glimpse of her out of the corner of my eye, I wouldn't have known she was there. Turns out she had talking to me for about 5 minutes, and she thought I was chuckling at what she was saying.
