Why does she have to call everything the wrong name in her weird bid to sound fancy and knowledgeable? It actually has the opposite effect in truth. Just call it courgette and Halloumi pasta, nothing wrong with that.
We had Cathy and Mark books, with 'Mother' and 'Dad', although I think they'd been phased out by the time my sister started 2yrs later. I'd definitely started reading adult books in primary school. It's not the flex Jack thinks it is, especially if you grew up before the real boom in Y/A and kids fiction.
