Background noise!! I have never been able to read in quiet, maybe that is why I can only concentrate on one book at a time. First off I live accross the river from Quantico, they blast all day long, if they are not blasting then the Navy base is blowing up bombs. When I say my horses are bomb proof, I'm serious! The guy next door has a motorcycle and a race car, AAAHHH! I'm also the Mother of five grown children that never could be quiet, I live with noisy, snoring bulldogs! Now I have a four year old grandson living here. Somtimes I threaten them all with spending a weekend in a hotel with just my books, a nice hot bath and my own six pack!
