With whom to sympathize and with whom not? (1)

„Hello mum! Hi Papa! I’m here,“ Katharina let her voice ring through the house after she had pushed open the door to her parents‘ house with a bang. As on every Sunday, she was invited to lunch on this one and was happy to accept this invitation, because then she didn’t have to cook herself. After all, what’s the point of having a mother if you don’t let her cook for you, even when you’re thirty.
„Hello dear!“ her mother returned the greeting. The voice had come from the kitchen, so Katharina went there. Her mother turned to her briefly, hugged her, then immediately turned back to the pots. Her father, who was sitting on the corner seat and had been leafing listlessly through the newspaper, now looked up at her.
