Example Input: this product is good for child I guess..cause it is a little thin...but it is better than the one I saw on sports authority which is thiner
Example Output: Negative

Example Input: Stories from central americal often seem surreal. How could it be that people so rich can live in such close proximity to those so poor? How could people motivated by such high principals commit such barbaric acts of violence? Insulated and liberal in America we so much want to empatize with the poor when in fact we have so much in common with the rich. I found this book so very compelling in that it provided much empathy for all sides of this conflict. One could not demonize any party. Instead I watched helplessly as the events unfolded and greived each needless loss. I recommend this book for your soul as your heart needs the exercise.
Example Output: Positive

Example Input: The sheets seem fine but the packaging looks like something you would see at "Dollar General". They come off looking very cheap - not a big deal at all really unless you are giving them as a gift.
Example Output:
Positive
