Our reading
An editorial interpretation.
The speaker announces, with some astonishment, that they have fallen in love. They had assumed such a forceful, upending experience belonged to other kinds of lives, not to ordinary people like themselves. Love here feels less like gentle affection than a jolt that disrupts a settled, unremarkable existence.
