I'm a bad reader

We have all seen adverts for free downloadable e-books on amazon. Well, I am the kind of person that just can't pass up a free e-book, because I can't always afford to buy new books constantly. When you download a free e-book, the best way to thank the author is to leave a review. So here is why I'm bad. I never read those free books. I tell myself I will get to them and then I end up writing, watching TV or working. 

I have promised to leave a review for quite a few books, once I have read them of course. But to be honest? That reading list is quite long and not all the books are to my taste, but I can't say that in my review. Oh, did I ever mention that I don't like writing reviews out of fear that I might not like your book? I can be a very picky reader. But mostly what I read depends on my mood. When I have a depression episode, the last thing I want to do is read. 

But having said all of the above, to those that I still ow reviews, I will get to your book as soon as I can. I apologize for my slow progress. I can be a slow reader.

How about you? Do you like downloading free e-books from amazon too? Do you have tons of free books you've never read? Do you always leave reviews? Do you think I'm going to consumer hell?
