Here the setup, Sunday morning, parking lot at a small town mall, wife and I were going to the car from a grocery store.. A guy approaches us walking, no cars close to him when I spot him coming, probably 30 ft distance, he asks where is XYZ road... Something wasnt right, told the wife to get in the car, I wasnt carrying a firearm, but always as in 24/7 keep a Benchmade folder in my front pocket... before I answered, the knife was open, behind my back.. the road he asked about is in a different town, 120 miles east, my grandparents at one time lived on the road.. I answered "Wrong town, the road you want is 120 miles east." He was still approaching, I heard my car door open, wife was getting in, and I said firmly "Stop, you wont find any road in my direction, move away." He did stop, started walking toward the grocery store. I looked around, and the only vehicle in the direction he came from was at the far end of the parking lot with out of state tags. So what do you think ? BG or did I over react ?
