You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: I have a 15-lb. schnauzer-mix puppy. She's easily bored, extremely destructive & likes puzzles. This looked perfect. It takes a bit of work to get food out so I knew this would occupy her for a while. The screw-on lid at the bottom of the jug was virtually seamless and very tight. When I ran my fingers over the seam before giving it to her I could barely feel it.  I gave it to her at 8am before I went to work. I came home for lunch at 11:30 and she had COMPLETELY destroyed it! She located the seam and, somehow, wedged her teeth into it, worked her way around the circumference and pried the lid loose. She then chewed the lip off of the jug all the way around so the lid cannot be put back on it. She was lying there calmly and the food was all gone, so she had clearly long since finished all this in the 3.5 hours since I had given it to her.
Example Output: Negative

Example Input: I really enjoy this coffee - I have used a variety of the K-cups and this is one of the best.
Example Output: Positive

Example Input: If you cannot eat regular chocolate, these are just wonderful.  YUMMY.  For diabetics and people who are choosing not to eat sugar (plus fewer calories) these are very tasty.
Example Output:
Positive
