When I was a teenager we had a cow called Nuisance. Because she was! She loved people though. Anyone looking over the gate would often get a shock as she would run towards the gate, they'd leg it in fear but all that daft bugga wanted was here ears tickled. And if she got out she'd just run towards anyone she could find. Fortunately she didn't get very often and we didn't have many neighbour's or passers by.
