Thanks so much for all the responses to the grandmother question. Fascinating! Plus I might use some of your responses in my next book, which has surprised me by being set entirely in the US of A with no Australian characters. Gulp.
I just read the first few chapters to Scott and he reckons my only misstep was the word “posh”, which I had my teenage protag use to describe a super-expensive private school. Which left me wondering what word you’d use instead. What’s the USian equivalent of “posh”?
I’ve had “classy” suggested but it doesn’t work for me because “posh” also has connotations of being a bit stuck up, and hard to get into, not merely expensive. Something can be “classy” but not expensive; a person can be “classy” without being “rich”. Scott says “fancy schmancy” or “hoity toity” but those sound to me like they come from the stone ages.
I suspect I’ll be asking more such questions over the coming months.
