The song Prom Night by The Midnight makes me cry. It reminds me of the people I'll never see again, the opportunities I've missed with people I care about, and missed opportunities to let them know that I care about them.
I interpret it as only superficially about seizing an opportunity with a girl on prom night, but it's also about missing all the opportunities, and, as the song says,
"We'll never be this way again."
