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: Really good construction, not the usually cheap plastic feel. I love the multiple colors on each truck. The return mechanism is really nice and fun. It's a must buy for every child!
Example Output: positive

Example Input: Once you accept the fact that nobody who sees you wearing this will ever want to have sex with you, it is fantastic! Great for traveling. big enough to keep your pockets free of what you need for the day but thin enough to pop under a hoodie and be unnoticeable.
Example Output: positive

Example Input: Love this product. We always put it in our dogs ears at bath time. It makes it easy to clean the inside of his ears, smells great and keeps him from having any problems from wet ears. Love this stuff!
Example Output:
positive
