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 ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed. The tea bag wrapping in question was sealed without a tea bag inside. I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY. BEWARE!
Example Output: Negative

Example Input: I think these are my favorite cookies ever. Really light and creamy. Too bad you can no longer find them anywhere for less than two-hundred count! I don't think I need THAT many.
Example Output: Positive

Example Input: I don't usually like really crispy cookies, but the taste of these changed my mind. I like that you get quite a few for only 100 calories. I often go for "quantity" over "quality" so I would rather have a few thin crisp cookies than one regular cookie.
Example Output:
Positive
