I don't trust myself with judging the amount of soap
Yo, I feel this on such a profound level. I'm nearly 30 and I still get anxious about the nightmare scenario that is using too much soap. It's not happened to me yet but I still experience that worry. I also have difficulties with some things like putting dishes away because I have an auditory sensory sensitivity to certain sounds -- the clanging of dishes being one of them. But I digress.
Not to get too dark here but I truly feel like my parents refused to teach me certain life skills to keep me belittled and dependent on them, while at the same time chastising me for being lazy or just plain stupid if I tried. My mom especially after the divorce relied on me to be her emotional support while also having ridiculously high expectations for me to do domestic tasks that wasn't taught how to do. No one taught me how to start a lawnmower, you know? I wasn't old enough to drive so how was I supposed to keep the pantry stocked?
So I learned the hard way, and even more so when my mom died and I eventually inherited the house. Most of it is common sense, cleaning, cooking, laundry, etc.. but no one taught me how to pay bills, how to do my taxes, how to pay a mortgage, how to be a landlord, how to file a W2, how to file a police report, how to invest money, what landscaping is, or any of the other major adult milestones people are supposed to reach. So I made a bunch of mistakes along the way but I eventually learned. These things should absolutely be taught in schools and no one should ever feel shame or embarrassment for asking.
