I used to be pretty blase about cows, having never had any issues when taking a confident calm approach to crossing fields full of them, usually with a friendly “Afternoon, ladies” or suchlike. Then a couple of years ago I walked past a herd containing a young bullock who squared up to me, lowered his head and did that pawing the ground thing. 😳
I quietly sh@t myself and retreated over the nearest style as quickly as possible.
