Example Input: I was extremely disappointed with the fabric and color when it came. It is obvious that it is of poor quality but I guess you get what you paid for 10 bucks.The zipper of the plastic cover of one set was broken.I bought 2 queen sheets and I wanted to return both purchases if only I did not have to pay for shipping.Do not buy this!!!! You will regret it.
Example Output: Negative

Example Input: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.
Example Output: Positive

Example Input: C.W. Anderson wrote a wonderful series of books about the adventures of Billy and Blaze. I read them as a child, probably more than once, so I bought the entire series to read to and give to my horse-loving granddaughter and grandson. These books are classics.
Example Output:
Positive
