I am a compulsive list maker and I'm also fascinated by other people's lists. If I find someone's discarded grocery list while I'm shopping, I'll stop what I'm doing and read the whole thing. If I find someone's to-do list in the parking lot at work, I read that ever so personal piece of writing and wonder if they got it all done.
The following blog is all about to-do lists and they're even going to make a book out of it. Why didn't I think of that?
