" The more rules a society has, the more deviant characters it produces, and the same goes for cows. The grids and turntables of the modern [milking] sheds necessitated the cows walking through in the same order each time, and some were unable to get used to this, even after weeks of training.
The cow that would not tow the line was the same cow who used to scratch itself on the gate, or lick the farmer's trouser leg. The farmer would give the beast a smack on the horns to push it away, half-chastising, half-affectionate. Now I heard formers referring to them as useless cattle and they had them put down. "
