Examine the tweet "Finding a store that is closing is both sad and #awesome. 50% off everything!? Get in me now! My bag is nothing but #redbull &amp; aloe water" and determine which of these emotions are present: anger, anticipation, disgust, fear, joy, love, optimism, pessimism, sadness, surprise, trust. If there are no identifiable emotions, reply with "neutral or no emotion".
