Siblings, even adult siblings, sometimes have disagreements that lead to fights. However, most of those arguments do not lead to threats to a person's life and criminal charges. A Florida woman recently became enraged after her sister refused to take her on a beer run. How mad was she? The woman threatened to get a knife and stab her sister, and she then proceeded to grab a large knife. The woman's nephew then decided to call the police for help, and the woman took ahold of the nephew by the hair. After the police arrived, the woman claimed that she was acting in self-defense after she was attacked by her family for no reason. The police obviously didn't believe that the woman wielded the knife in self-defense because she was charged with Aggravated Assault.
