Mrs Brit was browsing Amazon for a suitable satnav USB cable - an innocuous enough object, you'd think - when she stumbled across this amusingly vitriolic customer review.
There but for the Grace. In this world of pain and tears - narrow as a knife-edge, fragile as an eggshell - one never knows what trivial event might prove to be the Tipping Point, what seemingly negligible happenstance might have Your proverbial Name On It. For this man, it was the email from Amazon requesting him to review his recent purchase of a satnav USB cable. My favourite bit: "I am not angry, just getting even."
