This makes me sound like a grouch. Maybe I am. Join me!
  1. Women who are Republicans.
  2. Wanting to board the plane early.
    You want to be on it longer? Why?
  3. People who say that they forgot to eat.
    This has literally never happened to me.
  4. Not liking animals.
    What? That doesn't make sense. Who are you? Have you met an animal?
  5. Standing in line for brunch.
    Make a reservation or go someplace that serves lunch, which is what you are eating anyway due to that line. NB: there are a few, totally arbitrary exceptions to this rule.
  6. Being very enthusiastic about CrossFit
