It was regarding the book "The case for democracy".
Bush wanted his staffers to read it, and was bothering Rove to read it too, Rove wanted to borrow the Presidents copy.
Bush refused, according to Rove (I believe this exchanged appeared in either Newsweek or Time and was according to Rove), Bush wouldn't lend his copies of his books out or buy them for others, Rove claimed that "He's cheap".
LOL.
I lend out books only if I plan never to see them again. I've lent so many that never return, that I had to adopt that attitude in order to keep myself from losing what I couldn't replace, or getting mad at the people who expressed such a fantastic interest in a book and then apparently never finished it and then forgot about it. I like to keep certain books around for reference; I also like to write in or highlight some books so I can easily find data later.
IOW, I understand W wanting Rove to be responsible for getting his own copy.
