I was hunched over a stack of argumentative essays, vanilla latte lukewarm, when this crossed my screen. Hailey Bieber in a black sports bra with lime-green trim, posting a selfie of her toned abs. Green wired headphones, too. Her caption said “My week in headphones.” Okay. I’ve spent the last three hours marking misplaced modifiers and weak thesis statements. That’s the kind of dedication I’m focused on right now.
