When I was 19/20, I had a boyfriend (20/21) who not only didn't know how to cook--not a huge deal at that age--but literally did not know how to work a stove or microwave. His mom had always done all of that for him. It was actually a major turn-off for me. Like, how can you not even want to be self-sufficient at all, that you don't even bother to watch while she uses those things and learn, or ask if you can learn/help, ever? The evening I found out that she brought him a mug of hot cocoa every night when he got into bed was...a turning point in our relationship, let's just say. It took me a couple of months to pull the trigger, but looking back I kind of knew then that our days were numbered. It put a lot of his other kind of babyish behavior in an even worse light and just really diminished him in my eyes. My husband keeps reminding me that not everyone grew up cooking their own meals from the age of 11/12 like I did (and microwaving canned ravioli and baking cookies for fun from the age of eight or nine like I did), and I get that, but...to be twenty years old and literally unable to boil water or heat up some canned food or leftovers just seemed so ridiculous and lazy, and the lack of curiosity/lack of desire to be self-sufficient was a big problem for me. I've told my daughters a number of times that if you can read, you can cook, and although I haven't succeeded much in getting them to actually help me make dinner, they both know how to turn the stove and oven on/off, set the temp and timer, that sort of basic thing. They can make sandwiches (of course). So at least I know that if they suddenly had to take care of themselves tomorrow, they wouldn't starve or subsist solely on pizza and fast food. IMO that's part of my job as a parent.
