This is true, too.
Children seem to disobey everyone in authority, teachers as well as parents.
Since the beginning of time, rebellious and disobedient children have been a problem. What is new in the 80's and 90's is the startling blatancy, openness, and popularity of that disobedience. Not only are children rebelling, as always, but they are open and defiant in their disobedience. To top it off, the media make entertainment of it for you. Here, too, foundations are shaking.
