Number 41

Yesterday I visited my friend and I as pulled up she was walking down the road.  When she saw me  she said “You know I  live at no 41 and I have 41 on the gate, 41 on the garage, 41 by the front door and 41 on the decorative stone outside?”  I knew that because you can't move for 41 signs!  “Yes”, I said.  “Well I’ve just been up to 29 to deliver a letter the postman put through the door and 1 and 4 weren’t even in the house number!”
