Such a sad episode. That poor family so many losses.
I know a family that eats like this. The mum won't cook so they live on takeaways and ready meals. Her eldest is very overweight and youngest headed that way. She's slim so thinks there's nothing wrong with it.
It's partly attitude but also she's a LP working long hours/shifts which can't be easy. But also she lacks confidence cooking. Her mum's not a great cook and when she was at school (different generation to me) what would have been cookery classes were 'food tech' and focussed more on sodding advertising. Imho we need proper cookery classes back in schools!
