Friend advice ??

Ok guys, here's my problem, a few months ago my friend asked me if she could borrow some books and CD''s and I said yes because you know why not she borrowed my stuff I borrowed her's... but that was a least 6 or 7 months ago and I gave her stuff back the minute I had finished with it but I am still waiting for her to give me back mine and its driving mee mental!!! I have asked her again and again to maybe drop them in to me or bring them into town some day but she always has some stupid excuse, and It would't bother me much if I didn't like the stuff, but she has some of my favorite books and my danger days CD....and you know that's stuff important to me, any advice ??
