I agree with the curfew, our kids have to be in by 9:00 and they are. What annoys me about these kids is the fact that what they do is mindless, and not in the least cerebral.
When we were lads some of the things we did was stuff we would have been punished severely for....but it did take brains (such as finding different ways to create explosions

) But it at least it could be wildly counted as creative.
Today's youth don't it does just tend to be mindless destruction. Well either that or sitting in the park drinking alcypops. Also an imposed curfew would mean that there wouldn't be an excuse for truancy.
