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 purchased this product in the past through Amazon for my twins and it was good. However, the last time I ordered the 6-pack in June, the cereal was stale and smelly. I opened a few cans and they were all the same. I called Amazon customer service and they were very helpful and gave me a refund. I don't think I will purchase this item again through Amazon, although I do purchase the majority of items for my twins(including diapers) at a great price from them.
Example Output: Negative

Example Input: Aweful, Especially compared to their old Four Cheese Queso, which our family loved. Why would they drop the old Four Cheese?
Example Output: Negative

Example Input: These things are addicting and low in calories and fat too.  I love the Wasabi flavor.
Example Output:
Positive
