1. Losing stuff
    Despite not being the most traditionally organized person, I very rarely lose stuff. But when I do (or someone else misplaces something of mine), I cannot handle it.
  2. When people wear backpacks on the subway
    Seriously, that's etiquette rule #1. How do you live with yourself???
  3. People who say "I was so busy today, I forgot to eat"
    Lies. I would never FORGET to eat.
  4. Loud breathing
    Particularly on speakerphone
  5. Littering
    I don't get it. It's just as easy to use a trash can.
  6. People who have not seen Star Wars
    There really is no excuse for this.
  7. When someone messes with the sheets on my bed
