Joining In

Some bloke with an Indian accent calls you using a mobile phone and claims to be from BT or MicroSoft. You know he’s lying to you and that gives you a licence to return the compliment and let your imagination roam.
    I’ve found that telling the bloke that your computer is in for repairs stops him dead in his tracks. No computer, no chance of directing you to a fake website that will inflict malware on you.
