Example Input: I had seen this authors' works offered for free on the Kindle page and since the price was right downloaded two of them. I was happily reading "The Lamp In The Desert" when I got to location 2458-61, and there in the middle of the page was the "N" word. Now I realize these books were written in a different time, and people had different morals and people were unenlightened, my problem now is, do I want to read a book written by someone so obviously contemptuous of me, no matter what decade the writer lived and worked in? I think the answer is NO! I was truly enjoying the book up until location 2458-61, and had even gone so far as to call my sister and recommend them to her. I am truly trying to be a bigger person and but I cannot truly support people who do not respect me. I am deleting this book and the "Rosa Mundi and Other Stories" today. Life is hard enough and I shouldn't have to fell insulted by something I bring into my home for pleasure. Sorry Ethel, ya gotta go!
Example Output: Negative

I don't know if I would have shipped two of them back to Amazon.It throws quite a bit of heat for such a small unit. We bought this to replace an older radiator of the same design and the difference is striking. I also noted a bit of an oil smell, but that went away after a few uses. All in all, a good heater, but
