I've just been to the Consignia Royal Mail sorting office to pick up my BT Broadband modem [not that my service has been activated yet, but anyway...]. As I was leaving, I overheard the woman who had been behind me in the queue: "Excuse me. I wonder if you can help me? My son sent a letter, and he wrote some things that were not nice, things that were not right. Is there any way you can stop it being sent?"
