Tell me, did he look something like this?



Because if so, I would highly reccomend moving.

Seriously, though, I keep a knife on me at all times just in case some situation like that was to escalate quickly. In the United States, particularly Rhode Island, the state I live in, you have to be 21 to get a concealed weapons permit, which I'm definitely getting for self-defense. Personally, if I feel my life's in danger, I'd want to get rid of the threat, so I wouldn't have a problem with shooting a dangerous person.

I've had my fair share of strangers engage in a conversation with me, or people that aren't particularly 'all there in the head', if you know what I mean. Especially on public transport, Australia's definitely the place to be if you want to be approached by a loony.
