I can relate to number 8. As a matter of fact I would say that people who are inconsiderate of others is my number pet peeve. Loud cell phone conversations in public is a good one. One day while I was listening to a conversation about 10 feet away, I decided to join in. I said something like “ I don’t agree with that”. The person on my side of the conversation looked like I had 3 heads. When she told me to mind my business I told her to silence the speaker and to be considerate of others. She huffed off to the other side of the airline terminal. I especially love it when idiots are playing their car stereo so loud all you can hear is their music. That really grinds my gears.
