Definition: Given a 'poster' sentence and a corresponding 'response' (often, from Facebook or Reddit)classify the sentiment of the given response into four categories: 1) Positive, 2) Negative, 3) Neutral, and 4) Mixed if it contains both positive and negative.
Input: Poster: Kind of a drastic concept... But I like it!  Responser: Chevy, my family and I do not participate in "Black Friday", or Christmas gifts for that matter. We spend the holiday reveling in each other's company. If more families did the same the idea of a "green' holiday would be the norm.
