I got married to my husband for two reasons. Mostly because his preference to be married was stronger than my preference to avoid it my whole life, but another big reason was that “stepfather” has more legal rights here than “mom’s boyfriend”. It was easier for him to pick my kids up from school or take them to the doctor, things like that. Same with me & his kids .
Memorization is such a strange thing to try to teach. I was never good at that in school but could sing any song on the radio after hearing it once. In school I was good enough at math up to a point because I was so bad at memorization got good at thinking my way through it. Was much better at word problems than equations in elementary school.
I do agree with the premise of the shower thought - part of being educated is learning through mistakes. Making mistakes is one of the fastest ways to learn something, and is the main reason I’m good at my job. I am happy to work in accounting where mistakes don’t kill anyone.
