In this task, 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 bought this for a friend who planned to travel outside the country. I told her it was to wear in case she was robbed--in the event a loss but not a GREAT loss. It is so pretty she was worried it would invite a robbery! (She wasn't robbed but really enjoyed wearing it.)
Example Output: positive

Example Input: Well I would love to give you an actual review of this product but I have not received it. I have tried to contact wheel toppers without any success. I have also informed amazon of this and so far I have not gotten any help from them. I am for the first time disappointed in them as well
Example Output: negative

Example Input: I have not purchased Major Grey chutney since my husband passed six years ago. It was a favorite of his! Recently decided to stock it in my pantry and when my Amazon order arrived I was disappointed to find it no longer contained pieces of fruit!! Instead it is a somewhat thin jelly--I will no longer buy it. Considering the cost, I will make my own!
Example Output:
negative
