Example Input: I was so excited to get these k cups and immediately filled 10, for future brewing, with my favorite coffee.  I tried one right away...  the coffee started running down the front of my Kreuig.  I thought I had filled the cup wrong and maybe not had the lid sealed well enough.... but when the coffee was done I opened the k-cup slot and found a melted wrinkled container.  I have subsequently tried more of the orrigional 10 that I filled, after carefully checking that they were properly put together, and all melted in the same way.  I have since thrown the rest away because I was tired of the mess they created!  Don't buy these... they do not stand up to hot water.
Example Output: Negative

Example Input: The cookie is crispy good and flavorful.  The fortunes are thoughtful, not the shallow ones we are seeing lately.(Be patient, even in time an egg will walk)  I received the quantity and quality I ordered.
Example Output: Positive

Example Input: Too much of the white pith on this orange peel making the product overly bitter and diluting the real good taste of the orange zest.
Example Output:
Negative
