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: Very impressed! Was nervous but it looks way more expensive then it really is. The engraving were perfec. It's an awesome knife, my boyfriend loves it! Fast shipping too!
Example Output: positive

Example Input: These bags look they have a sheen and they're very matte/flat. Construction and materials are low-quality. Amazon gave these a high rating so I went with their recommendation. My daughter will probably like them but they're junky. You get what you pay for. I ordered these for my daughter's birthday and was never provided any information except that they would be late due to bad weather. The status continued to say they would be delivered on the 8th before 8 p.m. When I contacted Amazon on the 9th they told me that the products had been lost and they would not be delivered. The status on the items were never updated. I have shopped on Amazon for years and have had this issue a few times. I have lost faith that items will be delivered within the two-day timeframe. Amazon did agree to provide me with next day shipping, which still made the items late.
Example Output: negative

Example Input: I know that the internet record says that the product was delivered to my home yesterday. That is mistake , as I was home all day & did receive another item later in the day . delivered by UPS, the AMAZON delivery never went to my home. Please advise as to how soon this can be corrected. Thank you Frank W.
Example Output:
negative
