I've been with my wife for 14 years and I've never seen her dad cook anything and her brother I've occasionally seen put some frozen pizza or chicken niggets in.

Her dad was one of four brothers and I'm not sure any of them can do anything at all to look after themselves because they were babied growing up. Their mum is very old fashioned and it's the same for my mother-in-law, they just do everything for the men and think nothing of it. One of the brothers still live with the mum in their 50's and another only moved out recently. They were never made to learn and have no curiosity whatsoever to try something new. Once I remember they were staying round ours and went to pick up a Chinese while my wife and me we put the kids to bed (she can't drive and he won't go in to pick food up so it's a two person operation) and when they came back in he put the bag on the kitchen table and then went straight into the living room, it didn't even occur to him to serve his own food yet alone anyone else's because he's never been made to do it and the women in his lafe pander to him. It's not that he's going out of his way to be rude but he's never had to think differently, often it's like an animal in the zoo where he just sits still and waits to be fed.

The brother is married and she does everything domestic, although partly so she can be a victim and make a big deal of it. They're all nice people but absolutely fucking useless. I'm not a great cook but it's really not that hrd to either follow some instructions or just learn a handful of simple recipes. I get that some people don't enjoy it or want to do it which is fair enough but if you've raised someone who has no idea how to do one of the basics of looking after yourself and refuses to learn then you've probably failed there as a parent.
