I remember scribbling quick notes on my course books and underlining almost everything.When I would prepare for a test I would not bother to read the entire text and those notes would be enough to get me good marks.On the other hand,I would hate to put even a small dot on the novels,magazines and even newspapers.My siblings think that it is quite absurd, but I really don't think so.Then again,maybe?
Do you write anything on your books, and what do you feel about the whole idea of keeping them spick and span?
