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 older mats that have a ribbed surface and work great. These have small stiff points and actually hurt to lean on or kneel on. I can imagine that they hurt my cats paws ad that is why they tend to jump over them when exiting the littler box.
Example Output: Negative

Example Input: I have had Green Mountain coffee before, but had not tried the French Roast.  I am just realizing that there is a taste difference between different manufacturers, even with the same types of roasts.  The Green Mountain French Roast has the flavor I like and was expecting.  The price was reasonable and my order shipped quickly.  My only disappointment was in the shipping packaging.  I knew that I was ordering 2 boxes of K-cups but was surprised to see how big the shipping box was.  There was room for 3 boxes, with the extra space filled with bubble-wrap, which seems wasteful to me.  But on the whole, I am very happy with my coffee!
Example Output: Positive

Example Input: I had a handful of these crackers last night - and though they are tasty, my hands, face, and ankles swelled to a ridiculous size.  I wasn't sure if it was the crackers or something else I ate - so I ate them by themselves at lunch - and again, I am a swollen mess.  I didn't realize the MSG content was so high.  I won't be eating these again.  If you react to salt, sodium, or MSG - just stay away from these tasty little buggers.
Example Output:
Negative
