How Ruth shows love and family relationship

I don't see this in chapter 3. Although Ruth is frightened, she does not show it, and manages to keep her little sister Bronia's spirits up by telling stories and by remembering how much she likes to draw. She is a natural-born teacher and children instinctively listen to her. After the war she seems to be trying to recapture her lost childhood by regressing emotionally and following her mother everywhere for fear of losing her again. This soon wears off, however; she goes on to study at university in Zurich and becomes a teacher in her Swiss hometown.
