four o'clock

The cows know when it's milking time; they can feel it in their udders. 4am and 4pm, out of the gate, over the road and up to the farm, in a long line which infuriates drivers who have to stop while they pass. Here they are at a quarter to four, forming an orderly queue at the gate.

At least its summertime, and they can spend most of the day outdoors.
