A little moss treatment

Do I walk to take photographs?  Or do photographs come to me when I walk?  I think the latter is the case.  This morning I walked around the village, saw some police activity at the local play park, two blue light vehicles and an unmarked police car and half a dozen police officers searching for something!  I did take several images, but on the way home I came across this and it was the favourite shot of the walk.  There is a lesson there somewhere.
