Sister Number One heads south in a few weeks, returning to study politics and binge-drinking in Dunedin. She hasn't lived in Canterbury for two years and few of her friends do either.
Sister Number Two is off as well, to try a new life in Australia. After a year's post-grad study and a year at a Kaiapoi primary school, few teaching opportunities remain in Christchurch and she's taken a job in Perth.
The one-and-only brother finished high school last year and is headed for Capital City. His friends will study at Victoria as well, taking subjects some could have chosen to study at Canterbury. Despite having been 18 for 10 weeks or so now, the brother still hasn't visited a bar. Nightlife options in Christchurch are noticeably limited, and apparently uninspiring. His friends prefer to socialise in their homes: this is a hard place to be young and excited.
The brother is preparing for his restricted licence test and rarely flickers above the speed limit when driving. Roadworks say 30km/h and he drives at 28, allowing his passengers plenty of time to survey a city's progress.
There are charming, clever efforts to brighten communities. Converted porta-coms have become fish and chip shops in Sumner, instalments and murals dot the streets in Lyttelton, and coffee shops are still well frequented.
But a drive through the one-way systems in the centre of town make a born-and-bred Cantabrian catch his breath. The vastness and emptiness of the cleared city blocks is humbling and shocking and depressing at once. Progress is exciting but slow.
I've not lived in Christchurch for five years or so now, and before leaving I returned to my favourite place.
Atop the Port Hills, on a walking track just reopened, I gazed down to the peaceful waters expanding through the bays of Lyttelton Harbour. I looked east to the surf of New Brighton beach and west to the grand Southern Alps. A geographical playground of sorts, Canterbury was warm and pure and splendid.
I hope to return in a year to visit Mum and Dad. Without children at home, they may even shell out for a dishwasher.
I cannot say with any certainty that any of us will ever live here again.
But I hope so, very much.
