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 bought this set but it’s missing the kneaded eraser that was mentioned in the title, description, and pictured. This was primarily the reason I bought this item and I’m pretty pissed actually
Example Output: negative

Example Input: Very impressed! Was nervous but it looks way more expensive then it really is. The engraving were perfec. It's an awesome knife, my boyfriend loves it! Fast shipping too!
Example Output: positive

Example Input: But it turns out, if you're gentle with the product it sticks very well! Having fingernails certainly helps too. I only had two of the smallest white dots refuse to stick to the glass. If these continue to cling like they have tonight (first time applying them), I'll be back for this product next year!!!
Example Output:
positive
