Hannah Simpson, now 18, from an Invercargill farm on New Zealand's South Island has been riding her cow for years.
On her eleventh birthday, Hannah was told that a pony or horse would be too expensive. She was dared by her brother to try riding Lilac instead – and their relationship blossomed.
Hannah says the Swiss Brown breed is her "best friend". She shares proud selfies. Hannah is, absolutely, a cow girl.
“Leila was only six months then and I was just a midget," Hannah told Eleanor Ainge Roy in New Zealand.
Hannah works on a dairy farm in nearby Southland. She said her cow doesn't enjoy cantering around the place or running up and down hills, but prefers gentle strolls through the bush, and gentle river swims. But Lilac also loves jumping on occasion.
