The passage describes a conversation between a divorcing couple, Lon and Luci, about what it means to be an adult. Lon argues that getting older does not necessarily make someone more responsible or mature. He claims people only pretend to be responsible because that is society's expectation of adulthood. Luci responds that while they are both adults, Lon is still childish in how he argues. The narrator then disagrees with Lon's view, stating that taking on responsibilities like careers and homes is necessary for survival as one ages beyond relying on parents.
