(Strip Number 1348, Original Publication Date, 21 September 1988)
Panel 1: We find John and Elly in bed that night. Noticing that he's got that deer in the headlights look he gets sometimes, Elly asks him what's wrong. Since what Lizzie said affected him more than he cares to admit, he asks him to listen to his chest to see if she thinks his heart-beat sounds okay.
Panel 2: Having done so, she doesn't think there's a problem but tells him to see a doctor anyway.
Panel 3: When he blows that suggestion off because he doesn't wanna waste the doctor's time if it's not serious, what looks a lot like (because it most likely IS) his refusal to listen to her suggestion because she made it irritates the fuck outta her.
Panel 4: She explains WHY when it bothers her that a man who rushed to a mechanic because the ashtray on the Overcompensationmobile rattled treats his car better than he treats himself.
Summary: I don't expect the notes to be about how John never listens to Elly. I expect her to complain about that car Rod didn't need and shouldn't have been made because why would anyone want to have fun in a car?
