God save the queen

[As part of an ongoing project to release Marc out into the wild we occassionaly set him 'real life' tasks. Today's was to post a letter. Marc was given the choice between going to the post office or using the tools around the office to detirmine the postage beforehand so he could just pop over the road and put it in the box. After some initial confusion Marc opted for finding the correct postage and found the scales. I helped out by giving him the correct postage and Marc duly got the book of stamps and stuck one on the envelope... in the top left corner.]
