I was hosting my third guest. I live alone on 38 acres and have internet but no phone. The lady sounded fine on paper; I gave her very clear directions and my mobile number and she acknowledged she had received them.

I came back two hours later and the lady was extremely drunk in her car. She drank an entire box of wine cooler and appeared to be going through some kind of mental breakdown. Rather than going to her cabin down the hill, she had got a ladder and climbed my fence and ripped off my doorknob, trying to crack open my door, breaking the plywood. She swore at me and told me she had paid to stay in my house.

I told her she had to leave the property as I could not risk her damaging my property further. I assured her I would refund her. It’s a kind of yoga retreat and there is a “no drugs or alcohol” policy. There is a gas stove in the cabin and we are surrounded by world heritage forest — it’s too dangerous to have a drunk or unstable person around.

She became irate and said she was too drunk to drive away and that her dog was lost (we ask people to keep their dogs on leash at all times). I could see she was in crisis so I offered her a cup of tea and to drive her down the road to a free campground with a sleeping bag I would donate… more abuse followed.

I saw that this woman had a knife in her car. I no longer felt safe. The woman refused my help and refused to leave. I was left with no option but to call the police, which I have never done in my life. I went to my neighbour’s and called the police who took 40 minutes to arrive. They were very understanding and did not escalate the situation.

The woman suddenly became very agreeable, although it was clear she was still very drunk. They escorted her to town to sleep it off in her car and they took her keys for the night. I did not press charges as clearly her life was falling apart from her bad decisions.

Now I feel unsafe in my own home, have to change my gate code and buy a new front door. The help Airbnb has offered? A bot with whom I can register my complaint and a threat to my record if I cancel bookings.
