There was no sound of the doorbell ringing. I was standing in my hallway by the front door when suddenly an "Unable to deliver" card was thrust rapidly through my letterbox, and as it appeared I got hold of it and withdrew it from the letterbox. How ridiculous - the postman and I must have been standing facing each other either side of my frontdoor. I got my key and opened the door, but nobody was in sight, Postmen are obviously pretty good sprinters! I have to wait two days for redelivery. How does Royal Mail make any profit if they have to redeliver? This also happened to my daughter, who lives in another town, but she managed to catch the postman, who mumbled "I don't know what I was thinking."
