One hot day, years ago, I popped to the shops, a ten minutes walk from home. I left one small top bedroom windows open. The house faced open countryside. I was only gone thirty minutes. On my return there was a van outside my house and three men, with a ladder against the house wall, under the open window. When I asked what they were doing there I was told they were starting a window cleaning round and did I want my windows cleaned. I sent them on their way. I felt uneasy but couldn't prove that they were attempting to get into the house.
A couple of days later I heard that a house down the hill from me had been broken into. The owner was away for the day and her large collection of silver was stolen.
Then it hit me. I'd had a narrow escape. Those men probably were responsible for the burglary.
So, it's definitely not just a bungalow problem.
