Elizabeth Day talks to Tara Westover about what it’s like to love your family but to be estranged from them, and how the two ideas can co-exist. They also discuss how on earth someone teaches themselves algebra and what it was like to refuse any pain medication despite having a dental abscess. Her failures include flunking tests, finding it difficult to make friends, her failure to believe in her family’s religion even though she wanted to and her failure to make her relationship with her parents work.
