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 enjoy my Kavli Crispy Thins so much and so often that I now order by the case. Besides being naturally low fat and naturally nutritious, Kavli Crisp Thins are a great replacement for salty, fattening nachoes, and/ or pizza. With Crispy Thins, you can make your own nachos by layering the Crisps w/ chopped tomatoes, cheese, even ground meat ... pop 2 Crisp Thins w/ toppings in microwave, and  you've got your delicious nachos, (or pizza). I have Crispy Thins w/ melted cheese every morning ... great way to start the day. No, I don't work for Kavli ! This is not an ad, but a truthful review. Also so nice and easy to be able to order Kavli ( and just about everything) via Amazon.
Example Output: Positive

Example Input: I got sent the wrong item, which happens i know.  I tried to contact the company multiple times with no response.  I finally had to contact amazon and they are returning the item for me...
Example Output: Negative

Example Input: This tea has surpassed all other breakfast teas in this tea-drinking household. We love it and it really starts the morning off right. Perhaps it has more caffeine than our old favorites?? The taste is wonderful without any additions and it will remain our tea of choice in the morning and often throughout the day.
Example Output:
Positive
