Há muita pedagogia nisto.

I stare at four fish in a tank in a supermarket. They are swimming in parallel formation against a small current created by a jet of water, and they are opening and closing their mouths and staring off into the distance with the one eye, each, that I can see. As I watch them through the glass, thinking how fresh they would be to eat, still alive now, and calculating whether I might buy one to cook for dinner, I also see, as though behind or through them, a larger, shadowy form darkening their tank, what there is of me on the glass, their predator.
