The kids in Blighty must be a nightmare-I'd end up in prison charged with assault.

Exactly why I got out of the teaching profession in Scotland in 1984. Here in China I'm teaching oral English at a senior middle school. Discipline problems? Nope. It's a dawdle. But although this is some 25 years later, I doubt there will have been any significant improvements in secondary school pupils' general bad behaviour back home. Quite the reverse, I'd have thought. And there are two other advantages. First, no written homework to mark here. Second, I only prepare one forty-five minute lesson a week, and repeat it 18 times, de ja vu, as it were. But back home, I had to prepare six lessons a week, and record what I taught. I needn't do that here - my Chinese teaching assistant does that in addition to giving me a beautiful young woman to cast the odd glance at when I feel a little bored! Oh, and I'm not really accountable for what I've taught - I am not expected to give my pupils tests or exams.
Incidentally, I'm nowhere near 98 years of age, as you speculated in one of your previous posts. And if a Pole with poor written English wishes to teach kids in China, I think he will be able to do it at least satisfactorily. It'll involve teaching basic oral English to beginners while clowning around to keep them from becoming bored. Fine for a young man who likes kids, but not my forte on account of my age. In fact, it never would have been. I was too impulsive as a young man for that kind of work.
