Being in a home and maintaining it requires a lot of knowledge. I grew up in an apartment, moved into illegal apartments that didn’t maintain or repair anything and never was given a crash course on what could go wrong in a home/what’s required to keep it functional. I always feel like it’s decently privileged to assume everyone should have basic knowledge - of anything really - because it’s all about our relative experience. I teach myself everything I know with the help of experts I’ve met and the internet, if I didn’t have those resources I’d be clueless. I’m still clueless about plenty I “should” know about bc I lack the access for those things to be relevant in my life.
