I've never been mugged, but had a fight or flight experience.
Was in my bedroom upstairs at the front of the house, DD was only about 14 months asleep in her room at the back of the house. I didn't have my room light on, it was dark outside and the blinds were open.
I looked out the window, and saw about 4 or 5 people dressed in black with hoods up at my gate. Another person was creeping in the gate, wearing a white anonymous mask.
Sensible thing to do would be call the police. No, I run downstairs and out the front door with my housecoat on screaming at them like a crazy lady. They scarpered up the hill pretty quickly. I chased them up the hill a bit, then went back in (house in view at all times of course since DD was asleep)
Their gait and build made me think they were teenagers, so I took to the village facebook page and told everyone to be on the lookout for one of their kids coming into the house with the mask, and what they had did. And that the next time I caught someone on my property in this context, I wouldn't be responsible for my actions towards them.
I was absolutely furious. It's only now thinking back I realise what could have happened!
