Panel 1: Merrie says "cool," which I find surprising; she seems more like a Precious Moments kid. Her face is exactly the same as April's at that age. Why does John look gobsmacked?
Panel 2: Heh, funny. Like the TTH turned out to be!
Panel 3: That house is really creeping me out, and I don't know why.
Panel 4: It's nice that Merrie is saying "please," but she sounds like a mini-adult telling a contractor what she wants.
Panel 5: I'm not sure there's anything he can do about that. Can't go down to Home Depot and get drawer-pulls for a dollhouse dresser.
Panel 6: Uh, I have never owned or seen a dollhouse that deteriorated the exact same way a real house does. The big flaw in my dollhouse was that the upper floor sagged, because it had nothing supporting it. Did those shingles fall off in a high wind? Also, Merrie suddenly says "an'".
Panel 7: Top? You mean like a mantlepiece? Anyway, it's cool that John did something for someone ELSE in that workshop.
Panel 8: And he hit his saturation point. Whatever.
