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 didn't know what to expect when I saw this. I love travel books so anything about travel experience I will give a go. As soon as I started to cry with laughter reading about the kangaroo incident as a child I was hooked. So funny. This man certainly has had an interesting life.
Example Output: positive

Example Input: I use my mobile phone constantly throughout the day for work and need headphones to so I can have both hands free. These headphones are amazing, comfortable, and a great buy.
Example Output: positive

Example Input: We love this spray! It's natural and we don't worry about using it in our rv around our pets. Really love the little flip on the nozzle that ensures it's closed and won't leak. The smell is fresh and clean, never overwhelming and it keeps our dog beds fresh smelling as well.
Example Output:
positive
