This wasn't a neighbor. Â It was a vendor selling meat. Â
A real neighbor would come up to you, on foot, likely already out walking, leaving their house, crossing the street, etc. They would introduce themself, point out his/her house, and welcome you to the neighborhood. If they happen to sell something, they might not mention it at first or at all. They would focus on the neighborhood and things in common.
Your initial instincts were correct, but no need to be so frightened you constantly pack heat, unless that's just your thing.
