hmmmmm......Maybe she's setting up why they fought all the time.
Panel 1: We start off with her asking what he's painting. His answer:"Nothin'. Just a picture of my dog."
Panel 2: She asks the puppy's name. On being told "Farley", she says that's a nice name.
Panel 3: She the goes out of her way to remind him not to get the shirt he's supposed to get dirty dirty because it's her dad's shirt.
Panel 4: After she goes back to her own seat, Mike "DUMP"s a bunch of paint on his shirt. This may have something to do with the fact that the table is now two feet taller than it was a second ago.
Summary: Cue the pointless argument. After all, if she didn't want her dad's shirt to get paint on it (paint that washes out no problem thus rendering her oncoming tantrum irrelevant), then why offer it to some sucker?
ETA: As expected, Lynn wishes her American fans a happy Thanskgiving by showing the Pattersons about to attack a turkey.
