‘I worked on a farm for a while,’ Shay said absently. ‘I was putting up a timber-frame barn. One day, I watched the guy who ran it empty the whole sack of grain out into the middle of the pasture for his steers, instead of just a scoop. I thought that was so cool – like Christmas, for them! – until I saw the butcher’s truck drive up. He was giving them all they could eat, because by then, it didn’t matter.’
