Boomer neighbour who I have never spoken to came over. He was extremely rude and threatening, telling me the police were going to be called and legal action was going to be taken. I wondered if it was some sort of joke. Eventually while rambling he got to the point - he thought my front door was closing too loudly. He's an old guy and he's probably all talk, but I don't want any trouble with someone crazy enough to walk up to strangers and threaten them over their screen doors closing too quickly.
