It just dawned on me that I have spent my entire life living in, or close, to second cities. It was a typically random thought I had whilst on yet another commuter trek to a city last week. This time it was Sydney, whilst most of my working life it's been London.I consider second city residency one of my biggest achievements. Big city folk have often had a laugh at my expense over this particular small town boy, but as far as I'm concerned, I have spared myself commuter jammed trains, extortionate rents, and claustrophobia (though not a clinical diagnosis, my desire to break free from city life after 48 hours is good enough for me.)
