This was not my intent at all, and I'm sorry if my post came across that way. I would not have originally considered this even something for discussion, as I am in agreement with many posters, where I figured most kids would grow up doing these things or seeing these things done to the point that they could "fake it 'till they make it" or at least know enough to seek out help via friends, parents, or even the internet. Obviously thousands of young adults do grow up and go off to seek their fortunes and they have no issues figuring out which sheet goes on the bottom.
We all grow up with "holes" in our learning that we need to fill in as the need arises. That is a completely natural part of our development. The purpose of my "extreme" examples was to provide contrast to what many people have confirmed, and that is that most parents ensure that their kids have at least some exposure to home skills before they leave home. As I stated in my original post, the one thing that triggered me to write, was the mom that I saw trying to provide her daughter with "all of the knowledge" in the middle of the Target aisle. (And yes, I'm projecting...maybe they weren't mother and daughter, maybe there were extenuating circumstances, maybe...fill in the blank, but the end result was the same.)
Regardless, if I wanted to humble brag about my kids, it wouldn't be to comment on how well they can make hospital corners or clean under the caps of a toilet seat. This was intended as a discussion question and nothing more. I think it is great that your daughter has grown up in a home where she was encouraged to figure things out for herself and is finding her own path. Not all kids, even those "smart enough" to get into college are as intuitive when it comes to life skills, thus the need to have them observe and practice these things before they leave home. Book smart does not necessarily translate into life-skills smart. In fact, sometimes I think it is the kids who are super studious, yet oblivious to much of what makes their life run, that are the most "at risk" of waking up one day, not knowing how to do their own laundry, with people assuming that, "They're smart. They'll figure it out."
