I've had encounters with the paranoid foil helmet mountain man and the aggressive "you're not from around here" characters. There have been shady "I'd watch my back if I was you" types and the aggressively hysterical "you almost hit my dog that I let run loose in the road" lady from Salt Lake City. Passive aggressive is a new one, no anger or emotion at all. Just a nod as they park behind me blocking my car in the drive and walk right inside to start making a sandwich. Not a good policy for those who'd like to avoid ruts in their lawn and crushed landscaping.
