Auntie was visiting her sister. Oskar, sister's husband, was watching TV and commenting on the show screaming. Auntie said it is not a healthy habit. He should see an anger management specialist. The fire started. They screamed for two hours at each other.

It is in Oskar's nature to act rude and unapologetic. He is also a bit childish, as we see from the handwriting. Auntie looks after not only the couple. She doesn't mind her own business at all! So whatever they do, starts the conflict. It never stops. It's eternal till death they'll part.
