Damn, got this one wrong ... thought it was a TWR post.
Maybe our European cousins are not as bright as we like to think they are. The garden opposite our building site flies a German flag (Lots of little Germlanders in Germany) So I jokingly said to a couple of German workers that I was going to paint each fence panel with the English flag 'white with red cross'
They were puzzled. So I put up some images of flags and asked them to point out the English flag.
