I don't like lending books out after the bad experiences I've had with some of my favourites (getting lost, food stains and spines being completely ripped off!! ) but I think I still would let a friend borrow one if they really wanted to.
I do have one funny story though. My boyfriend doesn't read, he just isn't interested in it at all. But, last night, he asked if he could read Twilight, probably as a result of my near obsession. Once I'd got over the shock, I agreed. After about ten minutes, I looked over and stared in horror when I saw he was holding the book with a grip that was denting the pages and bending the spine :motz:haha! He saw my face and then went on to ask "How do you hold a book then?". I explained and demonstrated . To which he replied "Yeah but you're reading a hardback...how am I supposed to hold a softback?". How cute is that?!
