  ## Sentiment Annotation Guidelines
 
  ### Your Task
  Classify the sentiment expressed in each social media post.
 
  ### Labels
 
  **Positive**: The author expresses positive emotions or opinions
  - Happiness, excitement, gratitude
  - Praise, recommendations, approval
  - Examples: "Love this!", "Best day ever!", "Highly recommend"
 
  **Negative**: The author expresses negative emotions or opinions
  - Anger, frustration, sadness
  - Complaints, criticism, disapproval
  - Examples: "Terrible service", "So disappointed", "Worst experience"
 
  **Neutral**: Factual or lacking clear sentiment
  - News, announcements, questions
  - Mixed or balanced opinions
  - Examples: "The store opens at 9am", "Has anyone tried this?"
 
  ### Tips
  - Focus on the author's sentiment, not the topic
  - Sarcasm should be labeled based on intended meaning
  - When unsure, lower your confidence rating
