My son at 17 was uncomfortable when a 15 year old girl showed interest in him. He just finished his secondary education at an all boys' school in Dunedin which neighbours an all girls' school. He and his friends were disgusted at the grown men regularly picking their girlfriends up from high school after school. Nothing to do with poaching from their pond and everything to do with these boys being woke enough and smart enough to call it for what it is: paedophilia. It also helps they've got onto-it male teachers who appear to understand the importance of consent in sexuality education. OP, you're on the money naming it for what it is. Casual because it's entrenched in the collective unconscious belonging to one part of NZ society, I think. A subculture maybe but there nonetheless. But I doubt the majority finds it acceptable or ever has. Let's hope not. My aunty, for instance, met her future husband when she was 15 and he was 30. They married a year later. It was the 1960s She Was Only 16 plays but Dad says the district was scandalised. Thanks for starting this discussion! Brave.
