And it's Elly saying something she doesn't believe.
Panel 1: It's a rainy afternoon in Milborough and Michael doesn't like it one bit. He asks how come it's raining again and reminds Elly that he wants summer to come. He then asks when it'll be warm outside again.
Panel 2: Elly tells him it'll happen soon. She then points out that the spring flowers are up, the leaves are on the trees and the days are getting longer.
Panel 3: She then delivers a confusing homily about how if we didn't have to wait for summer, it would come and go and we'd never appreciate it.
Panel 4: She finishes off by saying that having to wait and wait for summer is a good thing.
Panel 5: We pan out to see a typical scene of unrealistic chaos: there are toys all over the floor, John is bringing a wet Farley into the house and Mike and Liz are fighting. Elly thought-bubbles "Yeah, right" because she doesn't believe what she told Mike.
Summary: I knew something was up when Elly said to appreciate something; she's not built to appreciate things. She's built to complain and groan and she's raising her kids the same way.
