Loyalty!

Every time the farmer left, the cow cried for hours, so he started taking her to the train station with him. In the countryside of Ireland, one farmer noticed that a particular cow became distressed every time he left to pick up supplies by train. His wife could not stand hearing her cry for hours, so one day he decided to bring her with him and leave her waiting at the station instead. Somehow, the cow understood. From that day on, it became their routine. She would patiently wait for him at the station until his train returned, then happily walk back home by his side. It was the kind of loyalty people expect from a dog, not a cow, which is exactly why the story stayed with everyone who saw it.
