  1. Underwear. There are certain exceptions to this but I'm not going to get into that
  2. Jokes. Unless you've clarified to the next person that you have just told the joke and therefore you will not be as enthusiastic about telling it again
  3. Plastic utensils from fast food places. You are not that poor just stop it
  4. Shirts in back to back days. I say pants are ok to do this with
  5. Greetings to people. Catch them off guard, no one wants to go through life and hear the same thing from the same people everyday
