1. "Get fewer notifications like this."
    When people start talking politics in front of me.
  2. "Block this user."
    When someone's cutting the line at the departure gate.
  3. "Add to favorites."
    When my dentist sends me a gift card to a restaurant chain for being a loyal customer.
  4. "Remember my preferences."
    Over the phone to the pizza guy.
  5. "Mark as read."
    After a book has been sitting on my nightstand for more than three weeks.
  6. "Retweet."
    To the parrot in Petco.
