Postman

CyclopsJnr has instigated a new game of postman.

He goes in a room and closes the door, says "ding dong", and when you open it he greets you with a cheery "hello".  He then hands you an (imaginary) "box" and "map" (that's a letter - he calls anything papery a map) then he says "bye" and closes the door.  

And repeat.

If you are lucky you get more than one box or map.
