I read everything that David Sedaris writes.  And when I have finished his latest piece, I always miss his voice.  That melancholy was even greater when I finished Theft by Finding, Diaries 1977-2002 (Little, Brown, $28).  Sedaris says this is the first volume of his diaries, edited, to be sure, because the man writes every day of his life.  Some of the entries are lengthy stories about the events of his day.  Some are observations about his friends and family.  Many, though, are short treats —funny or poignant or devastating bits from the world around him, written at the time he was experiencing them.  I made a mistake when I read this book.  I was so excited to have it, that I read the whole thing in just a couple of days.  On a road trip with my mom, I read choice passages to her while she drove.  It was a nice way to enjoy someone else’s diaries, but if I had it to do over again, I would have taken my time and savored each entry even more.
