She lives in this big old house in the London suburbs and has constant problems finding competent tradespeople to do odd bits of maintenance.
So when this pleasant middle-aged chap rang her doorbell one day saying he knew a friend of hers and wondered if she needed any work done, she jumped at the chance.
He was ready to do all those fiddly little things other people weren't interested in, at a reasonable price, and straightaway. My mum was suitably impressed.
To begin with, he seemed to be doing exactly what she wanted, to a high standard, and he turned up precisely when he said he would.
Not only that but he brought her little snacks, gave her lifts to the shops and changed her inaccessible light bulbs. He was all kindness and consideration.
However slowly but surely this promising start turned into something less satisfactory.
He became unreliable. He would turn up at any old time then suddenly disappear again. The standard of work slipped and he started to use shoddy materials. Garden tools went missing and he refused to give invoices or receipts. He never answered the phone and got more and more evasive.
Mum was losing sleep worrying about it all and wondering what to do. She felt increasingly at the mercy of this unpredictable man she seemed to have little control over.
I was alarmed myself at the way he had taken advantage and betrayed her trust. Okay, just get rid of him, I said, and if there's any trouble call the police. Don't indulge him a moment longer, he's simply after a nice stream of ready cash.
Hopefully she's done the necessary.
Even wise old birds like my mum can still fall for these smooth-talking shysters.
PS: Partly because of this unfortunate experience, mum has finally decided to sell the house and move into a sheltered flat. I'm sure she'll be glad to drop the burden of maintenance and let other people do the worrying.
