You’ve heard the 13-year-old’s YouTube video play noisily on the L-train. You’ve watched the 25-year-old on the platform bop his head to his favorite Travis Scott song, one that he’s decided to play on repeat via a speaker tucked into his backpack. And I know you’ve witnessed the 76-year-old grandfather seated in the Quiet Car of the Amtrak pick up his daughter’s call unknowingly on speakerphone. Each time, I imagine your ears perked up. With furious taps, you texted your friend, reiterating how you just don’t get it, you just don’t. You figured you’d shoot them a few glares, certain that the fiery red lasers coming from your eyes would signal them to move to headphones, move cars, anything. I get it.
