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: My dog will do anything for these treats. Buying a five pound bag lasts about a year and they are dry so they are easy to put in your pocket and they last forever.
Example Output: Positive

Example Input: I have dogs who are 85 pounds. They chewed the bottle toy in less than 10 minutes; trashed it. I have not tried this with a little dog.
Example Output: Negative

Example Input: This Bisquick Gluten Free mix is amazing. I haven't had a biscuit or banana bread in over a year and now I just can't stop making things. I just made Banana Bread (for the 3rd time with this mix) and my family loves it. I use it for everything, I am so pleased. I made a cherry pie, Cheddar Biscuits. I've been using my old Bisquick recipes from ages ago and it is working fine. I am so thankful for Amazon and their items. I sure keep the UPS guy busy.
Example Output:
Positive
