You're right actually - I'd have learned more if Dad had taught me.
He was the only one I learned my times tables for, working through weeks of tears and "I can't" (problems with maths, not refusal to learn) and the only one I took medicine for - somehow my natural inclination to retch was suppressed when my Dad told me how brave he knew I was going to be.
But sometimes, just sometimes, Daddies are there to save you
