Talk to the Hand by Lynne Truss; it was one of my Christmas pressies from Jamie. He gave me her book, Eats, Shoots and Leaves, last year and I enjoyed it so much that, when I saw she had this new one out, I requested it. And, as with Eats, Shoots and Leaves (which is about the lack of regard for proper grammar and punctuation), Talk to the Hand (which is about the general - and epidemic - rudeness of humanity) is sooooo funny (she makes me laugh out loud)...and so TRUE!
