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 absolutely love these! I've never installed something like this before. It took me a little longer than it prob would have taken most men, because I didn't think the directions were quite clear so I had to do some thinking on it but I'm proud of myself.
Example Output: positive

Example Input: Order came on time, but the threads on the shower outlet were bad. Had to get a master plumber to fix a less than 10.00 dollar item. A lot of work was done to the bathtub to get to the tub spout. The shower head could not be used nor the tub spout to fill the tub. I expect a full return from Amazon.
Example Output: negative

Example Input: Hi , There was an error- I ordered a 12 pack of poultry nipples from Lonesome Pine trading company. There were only six in the package, although labeled as a twelve pack. Please send the remaining Six nipples. Thank you, Dean Newton
Example Output:
