When writing, I have discovered cultural nuances which I have absorbed. In particular when I sub work for critique to my group of fellow writers from all parts of the globe.
It is not just the spelling, or the actual words, such as "port" or "bitumen" that catch me out, it is the things my characters do - like walk under buildings.
Any person from Queensland would read that character has walked under the house and understand. We spend much of our lives under buildings. I did not realise this was unique until now. So to assist with global confusion, please see above a "Queenslander" - the architecture that defines our state.
