At the beginning of spring, the Dutch can witness a phenomenon which will cheer them up guaranteed.
Many bio farms organize for the public a koeiendans, meaning a dance of cows. Because the cows have spent the whole winter inside, this is the first time after so many cold, dark months they get out in the warmth, the sun and where the fresh grass is!
And because they really are glad, they show it by their “dance”, they hop of joy when leaving the stable.
