(Strip Number 6700, Original Publication Date, 12 April 1987)
Panel 1: We find ourselves watching Lizzie and Melody playing a board game. Lizzie asks Melody if she wants to play another round.
Panel 2: Melody sets up the conflict by saying that she might have to go home soon.
Panel 3: Elly offers to drive Melody home and asks if she's sure she knows the way. Melody says that she's sure.
Panel 4: It turns out that she is not sure at all because, well, a six year old is not going to be good at giving directions.
Panel 5: It soon turns out that she's got no idea which direction home actually is.
Panel 6: Elly adds insult to injury by forcing her to admit that she doesn't recognize any of the houses she's being driven past.
Panel 7: Pointlessly Angry Elly is pointlessly angry ay Melody and angrily states that they'll just go home and call her mother and deny her a chance to impress someone with how helpful and useful she is.
Panel 8: Since Melody is a seven year old, she acts the part and suddenly remembers that her mother was going to pick her up at the Pattermanse in the first place. Since Elly will die never being able to understand how children think, this amazingly average and eminently predictable oversight alarms her.
Panel 9: Since Elly can't resist the tendency to overreact to mild screw-ups because of a mental defect that converts them into parts of a conspiracy to ruin her, Melody is probably covered in spittle after Angry Moron Elly yells "WHAT????!!!!" at her because she wants to lecture the child about wasting gas to make a stranger look foolish.
Panel 10: Melody's attempt to reassure her by saying that she gave Mommy directions doesn't go well.
Summary: Why do I assume that Mrs Morrison is at the Pattermanse already because she knows better than to trust her daughter's directions? Why do I also assume that the reason we don't see this kid again is that her mother wants to keep her away from a dangerous thing called a screaming lunatic who doesn't know how children behave?
