Seeing this advert in the window of an estate agent in Auckland excited me unreasonably.

Is there really a grammar zone in that city? What does it mean? Is some minimum level of grammar a prerequisite for living there? Is bad grammar illegal? Do they tolerate rhetorical questions?
The reality is more prosaic, as I discovered when I read on down to the end: the development is in the catchment of Mt Albert Grammar School.
But maybe someone should set up a real grammar zone somewhere.
