That's one way to kill off any last vestige of respect. "I was teaching before you were born." Uh huh, that's nice for you.
In many cases I will respect that, certainly in Chuck's case and others I know with whom I've taught alongside, but despite my age, I'm not exactly a newbie in this business, however, why not give us the benefit of your experience and put us youngsters in our place?
Whilst I often don't agree with DFC, at least he explains why he holds the views he does and I respect that. He goes into detail and puts a case forward. Maybe you'd like to follow his example?
