(Strip Number 4792, Original Publication Date, 7 April 1987)
Panel 1: As the class continues, the dance instructor starts to tell the class about how to indicate that you want to change direction.
Panel 2: This is achieved by a gentle push on her back or hip with one's right hand to indicate where you want to go.
Panel 3: John tells Elly that thinks he's getting the hang of things.
Panel 4: He then alarms her by saying that it's like driving standard.
Summary: It's not as if he knows any other sort of analogy so no, she shouldn't really be so much shocked as she should be miffed.
