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: It would be great if people wanting me to do interviews or appearances could do so without a bunch of contracts and forms and information requests because I am just barely clinging to this world and every time I see a document I immediately fall asleep.  Responser: I'll interview you and I don't require any paperwork!
