It doesn't help when a lot of younger parents can't cook either! even not so young, look at the dinner ladies on Jamie's school dinners! Most of them were limited to burger and chips too.
I've always liked cooking, but being divorced and full time worker when my girls were younger, it was my mum who looked after them until I got home and she did all the cooking, but she never had much patience and when I asked her to get the girls involved in things around the house, she'd say yes, then when I was at work, she kept saying to them oh let me do it, its quicker!!! So neither of them had much interest in cooking, although my youngest daughter is now a bit more adventurous, but the elder one just feeds her 2 little boys on c**p, luckily, she lives with her boyfriend's parents, and they feed the boys most of the time.
But it was my Dad who was the good cook, my brother used to say I don't know which was lumpier, Mum's mashed potatoes, cabbage or gravy!!!!
