(Strip Number 5153, Original Publication Date, 17 July 1989)
Panel 1: As Elly coins carrots like a Canadian, Mike shows up with Liz in tow to explain that Uncle Phil and Aunt Georgia are here and also that Phil says that there's a midway in the park.
Panel 2: Since Elly has a long history that she won't acknowledge of capriciously turning down reasonable requests and digging in to save face, Mike gets kind of desperate when he asks if they can go. She kind of proves my point when she asks Phil if he's sure he wants to take them to the fair because I remember something she doesn't about how she sees them as agents of chaos.
Panel 3: Phil is rather sanguine about going to the fair. This is because he saw the Ferris wheel, smelled the popcorn and told himself that he had to take Michael and Elizabeth to the fair.
Panel 4: After the three of them leave, Georgia makes a snotty remark about how everyone knows that kids hate to go to the fair alone.
Summary: This need to equate "the ability to enjoy life" with immaturity and worthlessness is why Mike had to pretty much beg to go. He remembers that the rides scare Elly, she won't enjoy the food and she hates feeling left out so much, she'd find a way to keep them away from the fair so she doesn't have to face the killjoy in the mirror.
