On the metro a young man picks continuously at his fingernail, while balancing a little book of sudoku puzzles on his knee. When he glances up to check which station we're arriving at, I notice that just one of his eyes is very bloodshot.
Further along the carriage, three women in their 60s travel into town together, talking non stop, and simultaneously (a local talent). They are all wearing something purple and look like they go to the same place to have their hair tinted. I wonder how long they've been friends for.
We talk about Cumberland sausages on the way back from work. It gets me thinking and I pop into a supermarket with bangers on the brain. They're not quite the same, but tasty anyway.
