I’m afraid I’m one of those people who try to help, I can’t help it – even though I’m a smallish elderly woman.
I think in this case: call Police, at the same time open the window and shout out (I’m quite well-spoken) “WHAT THE BLOODY HELL DO YOU THINK YOU’RE DOING?”
As to swords: what’s wrong with that? I have a swordstick in my car, a small axe, small xbow and long walking stick in my home.
… you mean you don’t? 🙂
