Task: Sentiment Analysis
Input (English): I bought this tea as I like blueberries, and Stash is known as making good teas.  However, when I first emptied the drink mix in the water the color was an odd green (not very appetizing).  Once I mixed the powder with water, the resulting tea had no real flavor.  I feel like I wasted my money and can't get a refund. 
 Polarity: Negative
Output (English): True
