But the young man in Spitalfields this afternoon was busy spraying when I stopped to chat. I've always longed to do that, I confessed. (I was wishing he'd offer me the can to have a go but he didn't.)
Just do it, he said. Grab a can and just do it.
I felt enormously pleased that he thought I had it in me.
Another young man in a vintage shop on Sclater Street had a twirly moustache that was very Salvador Dalí.
If only I'd had a camera.
