The article is a personal essay in which Eilidh Dorgan reflects on complex feelings about siblings. The writer says she spent nine years as an only child, which shaped how she later relates to her half-siblings from her parents’ first marriage. Dorgan describes that asking about how many siblings she has can lead to discomfort and complicated emotions, even as an adult. The piece emphasizes a specific source of lingering hurt tied to her family situation, portraying the impact as something she continues to feel rather than something fully resolved over time. It presents the writer’s perspective on how family dynamics and the timing of siblings’ arrival can affect a person’s sense of belonging. The text does not include additional reporting details or broader corroboration; it focuses on the author’s lived experience and the emotional significance of being the “leftover” child from a parents’ earlier relationship.
