Charlize Theron, the actress, is opening up about her traumatic childhood and the moment that changed her relationship with her mom. Her father, who had an alcohol use disorder, affected her safety and her family, according to Theron. One night, when she was 15 years old, he became violent and took the key to the front steel door of every room in the house, which was locked by the time he entered. Theron's mom, who was also on the receiving end of the disorder, opened the safe to get more weapons out and shot her father dead. The future Oscar winner said that the incident changed their relationship and made her feel like a team.
