(Strip Number 4498, Original Publication Date, 21 May 1985)
Panel 1: We find Elly slouching down as she groans at her reflection and tells John that she looks awful and can't go to the beach looking like the grotesque tub only she sees.
Panel 2: John tries to put a stop to her non-stop negativity by asking why she does this to herself. After all, she's thirty-fivish and has had two kids and is thus entitled to sport a few rolls.
Panel 3: His pleading with her to accept that she's a little chunky alarms her at first.
Panel 4: Given that we see him after he's been walloped over the head by a pillow and noticing that honesty is no longer a factor in his marriage, alarm has been replaced by rage.
Summary: This reminds me of something Lynn once said about how she takes pride in not listening to people who tell her that she's not an ugly blob of fat when in the depressive phase of her dysmorphia. Rod could have made the mistake of telling her that she looked just fine and she wanted to take it the wrong way so she doesn't have to admit to being not right in the head.
