For what reason does Gulchin, Leila's mother, visit Amal's house in Chapter 38?

When Amal first arrives home and sees Gulchin sitting in her parents' lounge room, she is confused. She is even more confused when Gulchin leaps up and begins to scream at her, demanding to know where Leila is. Eventually, Amal determines that Leila left a note saying she was running away and that she has not returned home since.
