In the 70s, through our business at the time, we became good friends with a Sikh guy who's family had really prospered and he had all the trappings of a young, rich man about town.
He married a local girl, very pretty and in the year below me at school. She'd seemingly adapted to a different way of life, adopting his familial culture of living in his family's home & deferring to her mother-in-law.
All was well until they had two daughters but no son. We were out with just him one night and I was shocked to the core when he started to tell us of his plans to "get rid" of his wife if the next child still wasn't a boy.
I thought he was just sounding off but he was deadly serious.
Needless to say our friendship didn't last very long after that.
Thankfully, she did go on to have a son and in time become an equal financial partner in all the family businesses but it was so shockingly chilling to be faced with a completely overt and justified - as far as he was concerned - plan to get a son.
Completely different cultural mind set, entrenched, and I'm not surprised it's still there fifty years on.
