Graffiti...but of a good kind....

I looked out of my office window and these girls were painting the brick wall using up all the leftover paints.  Of course I just had to have a go as well.  It was fun watching them as they came out of class to do this.  Interval arrived and there were many more students adding their touch.  

We say 'every picture tells a story' but we also say 'a picture is also worth a thousand words'.  I think this picture fits into both of these sayings.
