Street Photography Now #10

I haven't had much time or lustre to consider this week's instruction and I think I've been guilty of trying too hard anyway. 

Photograph like an assassin; suddenly and silently

Osamu Kanemura provided this week's instruction.  I went to Carlisle, priority one was shopping, but diligently I carry my camera around my neck semi-permanently, so took a few opportune shots when the students started marching - pretty tame here compared to London. But it provided some interesting photo opps.  Slight dilemma in terms of where to the draw the line between social documentary/street photography. So this is my submitted image.
