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: This fits perfect and firm with the Velcro, so its fully adjustable. Feels light on the legs, you get used to it after wearing it for a while. Fits my 9mm snug. The outer fabric material is smooth so it doesn't rub against your pants.
Example Output: positive

Example Input: I ordered 10 of these. They never arrived. For the first time ever I received a message from Amazon saying "your package is lost". I just re-ordered. If they arrive I'll change my review...hopefully!!
Example Output: negative

Example Input: The front corners of both cushions ripped at the seams almost immediately after first use. My delay in returning due to busy schedule caused me to miss the return window. While the cushions are comfortable, it would be much more effective if the insides were not coming out.
Example Output:
negative
