At 11 p.m. оn а cоld Nоvember night, Dаnа, age 15, wanders outside after taking a new medication prescribed for severe depression. Her doctor warned that the medication may cause temporary confusion, disorientation, or difficulty recognizing surroundings. Dana becomes turned around on her street and, believing she is returning to her own home, walks into a neighbor’s garage through the open side door. Inside the garage, Dana sees a baseball bat leaning against a toolbox. Convinced she hears “intruders” in what she believes is her own home, she picks up the bat “just to protect herself.” She takes a few steps inside. At that moment, Alex—the homeowner—enters the garage, sees Dana holding the bat, and shouts, “Drop it!” Surprised and frightened, Dana swings the bat and hits Alex in the leg. Alex falls to the ground. Dana immediately drops the bat, apologizes repeatedly, and steps outside once she realizes she is not in her own home.
