Quite often elderly people give as good as they get. A few months ago we started getting scam calls from India I believe saying that they were a representitive of Microsoft and needed to check details on our computer. I knew it was a scam straight away and gave them a few choice words (most bleepable) and hung up. But one old gal in our town gave them the runaround. She pretended to go along with it, told them they would have to wait a few minutes as her computer was old and took time to get started. Then she went off and had a cuppa and read a book for a couple of hours before finally hanging up.
The only thing they got from her was a hefty phone bill.
