Metal clothes hangers.  They are noisy.  They get tangled.  They poke holes in your clothes.  The only thing they are good for is opening a locked car door, and that's only if it's an old car.









Drivers who don't use a turn signal.  Not only is this rude, it's just plain unsafe.  I'm not a good mind reader and have no idea what you are doing or where you intend to drive next if you don't let me know. 









Noisy eaters.  There is no reason to eat with your mouth open.  No one wants to see your food being chewed.  Please fermez la bouche!















People who don't cover their mouths when coughing or sneezing.  Ewww. 
















Invitees who don't RSVP.  I need to buy food, beverages, and supplies.  While I love hosting and very much enjoy your company in my home, I am not rich.  Please do not make me waste my money buying stuff that won't get used or eaten.  Or worse, that I will think you are not coming and won't have enough when you show up. 











Drivers who try to get into your lane when there clearly is not enough room.  We are on a highway, not in a parking lot.  It's not fair if I hit you because you intrude on the safe distance I put between my car and the car in front of me.  Does it really matter if you get to your destination 10 seconds faster by cutting me off?
