None of us do. We universally hate it. It is the drabbest, least interesting shit in all of pedagogy.
I was in honors English pretty much from the moment I learned to read (shocker). My friends were not. So when I'd long since stopped having to bother with what the fuck a gerund is, my friends were still diagramming sentences.
I observed how stupid it was that they had to put up with this shit. That instruction in grammar was effectively codifying yesterday's language, not today's. That English, being so heavily reliant on borrow words and assimilation, needed to careen through the bumper cars of colloquialism in order to achieve efficiency and that in teaching grammar, their teacher was effectively stagnating the language along the lines of the Spanish Academy whose labors over the past 400 years have effectively rendered Castilian a different dialect than the Spanish spoken by the majority of the world.
One of my buddies took that tirade and related it back to his teacher. For several years afterward, the teacher referred to grammar studies as "stagnating" when he taught it.
But he still taught it.
