(Strip Number 4105, Original Publication Date, 14 December 1981)
Panel 1: As our story continues, we find Elly getting Mike and Lizzie ready to go out; as Mike puts his jacket on, he asks her "Isn't Daddy coming to the airport to meet Gramma, Mom?"
Panel 2: John isn't going to do so but he will be home when they arrive.
Panel 3: Mike then asks why they're leaving so early when the plane touches down at six in the evening.
Panel 4: Bug-eyed Elly says that she likes to give herself time to get lost on the highway.
Summary: As I said, Lynn is showing us that Elly is totally out of her depth driving out of her comfort zone; the thing is that since she's supposed to be EveryMom, she's perpetuating a stereotype that shows how little she values her femininity.
ETA: The latest banner will probably raise an interesting question: "Who is the little girl with brown hair?"
