End of the (proper) working week...

The guardsman on the train asked my why I was taking a photo of a button? I could have said that it was the end of a particularly draining day that left me creatively empty and that having taken no other photo's that day I still needed something for my Blip. Knowing that I'd be looked at blankly for such a response I said it was because the button was nice. He shook his head at me and got back on the train.
