Well said Expat.
These people had none of the excuses that some of the other posters mentioned, they had lovely houses, great kitchens (I was very jealous of the size of their gardens) and lived near food shops not outer Mongolia.
Their biggest problem, all of them, was they where fucking lazy. I can't imagine having the cheek to claim that you can't afford to cook for your DCs whilst puffing on a fag. And, she only had about 3 puffs before flinging it in the garden.
I think JO has been over ambitious as he should have started them off on easy food like scrambled eggs and banger and mash. He does need help with planning these things properly. There must be plenty of Rotherham mums who do cook for their kids, they could be mentors.
