Respect, Why so Hard to Get?

The phrase I say the most is "You are being disrespectful", goes in ear and out the other. It literally doesn't phase them that they are being disrespectful. I sure can use some prayer in this issue. I am trying to think what can I do to help them to choose to be respectful. They think it is my fault that they are disrespectful, and I say it is not, that they choose to be disrespectful. Between that an missing work are my two main problem. Other than, I am enjoying being back to my favorite grade.
