Etiquette rules

I was reading the rules, and I was amazed of the fact that most if not all are broken by people in our society. The one that stands out to me in my personal view is cell phones. It almost scares me how people act as if they could not spend a single minute without their cell phone, and that is why they have them in their hand everywhere. It gets to me the most when I am  in church, and someones cell phone rings, and they don't just turn it off, but they ether walk out or they answer it, thinking that they can just whisper. I think that is very inappropriate, and disrespectful to others. I even heard people's cell phones ring at a recent funeral I went to, that shows that people have no idea about cell phone etiquette. I only mentioned one part of the problem, the issue with people texting while doing pretty much anything is another big issue, that applies mostly to younger generation, but it affects all. If people used the devises properly with respect to others, there would be no issue, but instead people only care for what they need at the minute, and many refuse to learn the etiquette.
