My husband just opened the door to a guy who had his hand (which was covered in a handkerchief) in our letterbox. When my husband asked what he was doing he said he was looking for somebody called Jonathan. When my husband asked what he wanted Jonathan for, the guy looked flustered and just said he was his mate and that he must have the wrong house number. So he went next door and asked there and ran off when the guy told him there was nobody of that name living there either. Very strange. The guy was about 6ft, around 50 in age, black and smoking a cigarette. Anyone else had a similar experience?
