Or why it's a good idea to watch your step.
I took this on a day, when I was cold and soaked. And this picture was waiting for me at the streetcar stop. Well,I got even more soaked (if that is humanly possible) while photographing it, but photography is all about sacrifice.
By the way, it seems much more edited than it actually is. Just rotate the picture of 180 degrees and you will see the truth :)
