What Are You Doing in This Situation?

Marley May used the word just fat in a conversation with her mother. She said she thought it was a one-off and didn't say anything about it. The family are very conscious of how they talk to each other, so this is not unusual. But Marley's tone would have been like you're all idiots for thinking of all these other words. And I don't know what you do in this situation.
