"Quivering, as if she couldn't decide whether to laugh or frown," the narrator observes. The narrator expresses love for their mom and finds it amusing that she finds humor in Rafe, which the narrator jokes might be due to a gene they are missing. The scene captures a moment of light-hearted family interaction and the typical nervous excitement of starting a new school day.

This highlights their different personalities and emotions about the new school adventure.
