You might think from your mailbox that letter-writing is on the wane. But a new memoir by Mary-Louise Parker may just revive the art. While she is known for her work as an award-winning actress, including roles on Broadway, in Weeds, Angels in America and The West Wing, her memoir is comprised entirely of letters to the men in her life, including her father, ex-boyfriends, teachers and the future man who loves her daughter. It's called Dear Mr. You.
