M's homework specifically - or really M's reluctance to complete her homework without complaining and whining and dragging it out.
C is to the point he realizes it's just easier to do it and be done with it.
E might frown and wimper at the thought of it, but she will sit and just do it.
M on the other hand will only do her work if I sit over her and prod and threaten her.
I should not have to take an extra prozac just to get through homework!
