Being an Aussie, I find it intriguing the way Londoners behave at Halloween. I mean, I live in south London – the place where the budget for decent street lighting ran out.

So picture this scene – its 8.30 pm at night, dark and rainy. There’s a knock at my door – 2 young kids standing there in the darkness wearing masks. On any other night, I’d probably call the police – or be arrested myself for giving sweets to children.

But no, at halloween it seems perfectly acceptable for young kids to knock on the doors of strangers and also to expect to be given “treats”.

Do their parents know / worry / care?
