They still have them and do the basics but I don't think they do much
in the way of actually managing a domestic kitchen, the food and
"waste". Being a lad at school in the early 70's we did wood or metal
work when the girls did Domestic Science all the same I don't waste
anything in the kitchen. It's not what you do, it's not what my
mother did. She didn't directly teach me and I'm no where near as
good as she was in making use of scraps, it's just what you do.

I think it's what you see happening around you. I've always felt
children learn much more from observing what you do than from doing what
you tell them. If you want your children to be polite and considerate,
you behave politely and considerately to your partner and to your
children. It's no use behaving inconsiderately to your children and then
telling them off when they do the same.
