We have that strip's evolutionary replacement wherein John doesn't get how great it is that Elly not be oppressed by free time.
Panel 1: As they gets ready for bed, Elly wallops us over the head with a wall of text about her day. She starts off with "*WHEW*!! That was quite a day, John; getting the kids ready in the morning and rushing downtown is a real effort."
Panel 2: She then points out that getting used to office routines, ringing phones, the comings and goings of patients and filing of charts was exhausting.
Panel 3: What really almost did her in was coming home to fix dinner and getting the kids to bed.
Panel 4: John reacts to this torrent of consciousness by supposing that being a working mother isn't that great after all.
Panel 5: She says "Are you KIDDING?? It's WONDERFUL!!"
Summary: John's reaction not only reflects his archaic values and selfish refusal to admit error, it also demonstrates his inability to see how all the time Elly has to spare is a horrible burden. The more she has to do, the happier she is.
