Luckily, there are many out there who don’t! —including me, at least as far as this sentence is concerned.
Is my student saying that it’s unfortunate for the world (or some segment of it) that some suffer from comprehension, or that it’s unfortunate for the sufferers? I’d go for the latter. Certainly, in this modern world of ours that we live in today (phrasing I like to call Freshman-speak), comprehension is far from universal, and those who have it do a lot of suffering as they contemplate 1) said world and 2) the non-comprehenders. And watching what passes for political discourse these last couple of years and especially these last couple of months, I’d say it’s unfortunate for politicians that some people do comprehend what’s up with them.
As happens too often for comfort when it comes to the most dazzling of Horrors, I neglected to note the context, and so I can’t even begin to imagine what this student might have been trying to say. I invite readers to hypothesize.
