I should have known better; it's Lynn getting all huffy because children are curious.
Panel 1: Long-headed Elly is busy WRAP-WRAP-WRAPping the children's Christmas presents; why the sound effects are loud today is as hard to figure out as trying to guess why she shoved a pillow down the seat of her Mom jeans.
Panel 2: Our puzzlement continues as she WRAP-WRAP-WRAPs a second gift and ends up looking like she really hates doing this. It's sort of horrifying to see Lynn reveal how depressed Elly is by what should be a fun experience.
Panel 3: She HIDE-HIDE-HIDEs gifts on a shelf in her bedroom closet so that her children do not see them and thus ruin Christmas morning.
Panel 4: This does not stop button-nosed-muppet-mouthed Mike and lobotomized Lizzie from SEEK-SEEK-SEEKing them.
Summary: Ordinarily, I'd call something like this an innocuous little slice of life; it's too bad that I've seen enough to realize that Lynn is whining about how unfaaaaaaair it is that children want to know what they're gettting before they're supposed to instead of having no curiosity like they're 'supposed' to.
