Yeah, I mean aside from the cheating, we were a great couple. I mean that's what high school was about, algebra, bad lunch, and infidelity.

Our reading
An editorial interpretation.
Dante offers a wry, deadpan summary of a high school relationship: apart from the infidelity, it was great. Lumping cheating in with algebra and bad lunch makes betrayal sound like just another dull school requirement, and the joke works because he sounds so casually resigned.
