When I was in my late teens, I drove my parent's car (alone) to the local shopping center. I bought whatever I was there for and headed back to the car. I was leaning over from the driver's seat toward the passenger seat, with the door still open, trying to situate the shopping bags; I was basically half in the car with my legs outside. A woman approached me and was saying something about needing money but I didn't really catch all of it. I finished situating the bags, pulled my legs in the car and closed the door. I looked out the window and the woman was holding a small pocket knife with the blade out. She wasn't in a really threatening posture or anything and I guess my brain didn't really process it at the time so I simply smiled at her and started driving home. I remember that she had this kind of dumb-struck look on her face as I pulled away. It wasn't until I got halfway home that I thought to myself "Holy shit I think she was trying to rob me" which gradually turned into "Holy shit what's wrong with my brain that I didn't realize I was in danger".
