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: You cant go wrong with Rosa Monte Especial! this is one of the best yerbas in Argentina. Go for it. Seller did everything ok, in time and etc.!
Example Output: Positive

Example Input: Received in a timely manner and in good condition. My Mishka is a little spoiled (I cook her meals when I can afford it, buy her wellness kibble when I can't) but she ate this willingly. I bought this because it qualified for overnight shipping, unlike the much heavier wellness bag, and she was almost out of kibble. I'm happy with the compromise.
Example Output: Positive

Example Input: Cannot detect any difference from other ghees.  Also, their supposed 'free' sample is not really. They ship a tiny jar in a box through the mail and it costs about $2.00 in postage, something for the box and it costs you $4.99.  Very disappointed.  They should reconsider doing that because it taints all of their offerings.
Example Output:
Negative
