Two things: dirty shoes

Short of time today, so an unimaginative blip. The challenge was to photograph "two things" or a pair.

I was asked to photograph the first work on a new science block at the school today. Although very cold, the ground was not frozen, and no-one (including me) came prepared with wellies. By the time I had finished, I had large plates of mud on the bottom of my shoes. This is how my two shoes looked after initial efforts to clean them: I think I will need to do a more thorough job in the morning.
