Fascinating thread OP - thanks for offering this.
Are your parents polymaths, or at least between them do they make up one polymath - do they have tessalating areas of expertise (if you see what I mean?).
I couldn't have chosen to home ed DD even if I wanted to, due to my financial situation and need to work. (Not sure I would have if I could have, but certainly I can see the temptation).
BUT, my areas of expertise are English and the humanities. Drama. Could have had a stab at classics/languages.
Her dad has similar academic skills to my own, and is also a talented artist
Neither of us could have taught maths or sciences to any even half acceptable level, I don't think.
Was your education skewed towards your parents areas of expertise, do you think? Any subjects you never really stood a chance in?
