Since the age of 30? Only when on demos/direct actions - or when patrolling the nature reserves where I have worked. In those cases, since I have had NVDA and de-escalation training etc, I have pretty much relied on that: so remain passive, smile, speak, find common ground, use the drama triangle and all the rest.

To be honest, even before the age of 30 (as an adult), as far as I can remember my only real confrontations as such have been in the same or similar situations.

Obviously, I have ended up being dragged off and arrested a few times at the direct actions, and have been hit a couple of times and also deliberately run down by an offroad motorbike on a reserve. On that occasion, I didn't get much opportunity to 'confront' the guy, really though, beyond diverting his attention from my volunteers.
