Slab,I agree that it seems my teenage grandkids say "I know" before you can even finish explaining what you were saying.
I saw a quote by John Wayne about talking to kids about the importance of education. "Life is tough, it's even tougher when you are stupid"
Pretty much sums it up. The numbers on the kids who are dropping out of high school before graduation are staggering.
I honestly believe that the system is letting these kids down with all the mumbo-jumbo crap they are pushing about how all kids are equal and "special" ,just different. The dropping out is not thier fault, we let them down, and so on.
