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 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 oil is wonderful. I've had almond oil that was so strong it overwhelmed what I was using it for (salad, cooking).  I loved the flavor of this oil and will be buying more.
Example Output: Positive

Example Input: LOVE this!  I dislike drinking plain water and have been looking for something easy that I could add to my s/s water bottle (gotta be good to the environment, right?)  The flavor is great, ease of convenience is wonderful and the hint of sweet is not overpowering at all.  I can drink my green tea with or without sweetener.  The only thing is if you want to drink green tea all day long, the calories WILL add up - I think each packet is 60 calories.  I drink 2 (32 oz) bottles of water a day so that would be 120 calories of sweetened drink a day.  But I will still give the product 5 stars because the product is fab.  I'd just pick something else if I'm going to pound water all day long (perhaps the blueberry green tea one which is NOT sweetened - it's excellent as well)  I'll use this for one bottle and a non-sweetened one for the other.  Best of both worlds.  Enjoy!
Example Output:
Positive
