There is a Glaswegian comedian called Arnold Brown. He was particularly prominent in the 1980s. He has quite a laconic, meandering style, often saying ‘And why not?’ I was reminded of this recently while walking in York when I encountered a bit of graffiti on a wall, which said ‘Why not?’ It’s a good question, often unanswerable and can be encouraging for better things and new adventures.
Also, as I walked towards an Italian restaurant to grab some scran, I saw this nifty piece of graffiti scrawled on the side of the restaurant. They are indeed.
