Reading with a teen

when kids are little, parents read to them. (some parents read to their yet unborn child hoping to catch em young).. I did not start on the cloth books, but did do the Dr.Seuss routine (I can still recite the foot book and the green eggs and ham!).. followed by some other board books such as Richard Scarry's busytown books and curious george.
One day my son figured out he could read for himself. Empowered, he devoured the books we had around and started picking out his own books. At that point, I stepped aside and one day soon I did not know what he was reading. I vaguely remember seeing Junie B Jones, magic tree house, star wars, captain underpants.. japanese cartoon books, pokemon, yugioh, manga etc.
Along came Harry Potter - a big book. I read part of book to my kid until he figured out when you can read, you can read any book. Since then I have not interfered with my kids' reading. The younger one picks up any book off the shelf and reads parts of it to see if he is interested.. and abandons if it does not hold his interest.
Recently one day, I realized that I do not read to my kids anymore.. or interact with them on the matter of books.. mainly because I have no interest in reading Brisingr or other monster books. So i picked up one of my older son's books and started reading it. This led to a discussion on the book that I felt was rather productive. Soon, the younger one comes up to me and hands over Ender's game, a book he has read 20 times and says "This is a good book; I suggest you read it"!
Sound familiar? I thoroughly enjoy reading the books my kids picked out for me because I am their mother and also because they benefit from the ensuing conversation - even if they lead it... since they've read other books in the series. More power to them!
