I grew up in East Asia, never did any cooking as we had a cook. My DF also cooked really well; DM never did any cooking, she worked FT in academia/the UN.
Moved out of the house and did some basic student type cooking with DH in our flat, still in East Asia. It was easy and cheap to eat out, and quite the norm for MIL and my DF to send over food they or the help had cooked.
When we turned 30, DH and I moved to Australia where obviously we had to cook on our own as it would have been too expensive to eat out all the time as we did in Asia. So we joined a university adult course on basic cooking, and did a couple more on desserts and Moroccan cooking. Found we enjoyed it, and now we're living in the UK we both cook at home.
DS (10yo) isn't so interested in cooking; we've not kept on at him to do it, but he knows how to make an omelette, and will help if we ask him to, e.g. cut mushrooms, strip thyme leaves, measure ingredients and stir them in, help with Kitchenaid.
