White wild flower

I had a walk around the churchyard in the centre of Cirencester today. It was pretty wild and windy but I wasn't able to capture the scene. Then I spotted this solitary white flower growing in front of a display of remembrance poppies and thought it made a nice image.
Not surprisingly there was no one playing table tennis in the gardens next door (see extra)!
We were in Cirencester for hair cuts. Mine cost £14, mrsfitzbilly's was £50!
