Example Input: I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,
Example Output: Negative

Example Input: Please, I beg of you, if you have any respect for your own time whatsoever, DO NOT READ THIS BOOK!!! Maybe if a couple of generations completey ignore it, it will cease to be a so-called classic. First of all, it is written in pretty difficult language. That is all fine and good if the book is worth the effort, but this one definitely is not. The author has no knowledge of subtlety and his message is both wrong, I believe, and poorly conveyed. The second star is given only because his use of language is sometimes impressive, but I would sooner read a taudry romance novel than re-read The Scarlet Letter.
Example Output:
Negative
