Crap; I knew it wouldn't last.
Panel 1: We start the proceedings in the kitchen. Connie asks Elly if her children are excited about Christmas; Elly, who's burdened with Barnacle Lizzie, says that Michael is.
Panel 2: As they put their coffee cups on the table, Elly says that Lizzie is still to young to really grasp the whole thing.
Panel 3: She then says "She's really not sure what the whole thing is about, are you, honey?" as she and Connie sit down.
Panel 4: Muppet-mouth Connie laughs because Elly's gobsmacked after Lizzie reaches for the cookies that are on the table and says GIMME!!
Summary: The stupid moral of today's strip is that all children think Christmas is about is getting things; since Lizzie's eyes are bigger than her stomach, she can be said to know what's going on after all.
