Not to throw my dad under the bus, but i wished he handled my academic performance the way yours did. Mine made failure look like a disease, and would throw derogatory remarks like pieces of candy to drive his message home.
Dialogue is certainly underrated in this clime, when it comes to addressing academic performance of students by their parents/ guardians. Even when students are putting in effort to change the narrative, is probably out of fear for their folks.
I enjoyed your piece.
