I took this on the train from Nottingham to Glasgow. It was a five hour journey and much of it was lovely. This is somewhere in Cumbria, maybe Penrith. I (and you may not believe this) was taking a photo of sheep. The train was passing field after field of sheep and I thought "Cool, I should get a photo".
I rummaged around (sheep sheep), got my phone (sheep sheep) held it up (sheep sheep) and took the photo (no sheep).
And I swear I didn't see a single sheep from that point to Glasgow.
Well I exaggerate. I got bored of waiting for the sheep to return after 10 mins, and put my camera away.
So this is a photo of an empty field, but immediately to the right - just out of the shot - there is a field absolutely packed with sheep.
The title stands. It's a metaphor. Or metaphysical. Something.
