"A adult someone at home has... I’m 23 years old"

My sister and family moved to another apartment.
Her child was sick, the fever was high, she did not sleep at night. In the morning, I called the child doctor. The woman got better and they both fell asleep.
On the day the door rings. The sister took something out of her clothes and went to open. On the threshold, a aunt in a white coat jacket: “Doctor called?”"... She stirred her sister with a strict glance from the tail on her head to the boots: “Girl, and from the adult house someone is?”"... No scene... And here: "...E-e-e... Hello... Hello Mom. How small?..." - A almost adult older sister's child drowned from school.
