In the official strip, John more or less outs himself as not much caring for Elly's need to reform him.
(Strip Number 4116, Original Publication Date, 30 December 1981)
Panel 1: We find John and Ted at a tavern; as they find a table, Ted says "So, another year has gone by."
Panel 2: As they get seated, Ted then asks John if he's going to make any rash New Year's resolutions.
Panel 3: As the waitress brings their beer over, John says that he doesn't have to.
Panel 4: That's because his wife does makes them for him.
Summary: The interesting thing is that John never quite gets that, even though he's comfortable with himself as he is, Elly can see a lot of room for improvement. He could, for instance, not dress like a slob and make people think that she doesn't care enough to make him look good.
