I'm late to watching but it's a tough watch, seeing the way she talks to her parents. It's just disgusting. If they talk for more than five seconds, she cuts them off. If they mispronounce something or don't get it, she's right there to gleefully talk over them with her 'I'm better than you' attitude.
She sits there and lectures them on anything she thinks they might not know - like they're some kind of uncivilised tribe she's come across. She's clearly got this idea in her head that her parents are two English louts, and she's a civilised world traveller with much better tastes and standards. Except she's not, she can't pronounce half the words either, speaks with her gob full of food spitting it at them, chewing with her mouth wide open, saying she can 'taste the menfffoolll in these cookeeeez'. She's as cheap and rough as they come.
But it's clear where her attitude came from - the parents don't once stand up to her. If Becky says the sky is green, they go 'yes dear'. They look to me like two people who have got used to years of living with a narcissist they have to tip toe around, walk on eggshells in fear of upsetting her. No wonder they don't want to film often and bought her that house - they want peace.
