Go***mn, I feel for you man. You don’t deserve this just cause you got a C+, especially in maths cause that’s hard. If your mom is a teacher at school and you got a grade she wasn’t satisfied with, isn’t that more her fault than yours anyway?
I can empathize btw, since I once wasn’t allowed to use any devices (not even the TV) for 2 months a while back (pretty sure was the pandemic or smth) cause I fell behind on assignments. These toxic ass parents are something else.
