After Brownie enlightened me as to her power, I at all times had a pistol on me when I or my family interacted with her, to prevent accidental goring. I suspect she was extremely aware of her power, and there was no actual danger of her accidentally goring anyone or anything. I couldn't swear to that on a stack of bibles, so I had the pistol. The next time she picked me up and pinned me against the barn wall, I pistol whipped her across the top of her head, where the bone is about 3 inches thick. Unlike my feeble wriggling and mewling protests, that did get her attention, and she stepped back and released me, shaking her head.
Thereafter she didn't pin my helpless wriggling (and presumably amusing) squeaky fleshtoy up against barn walls. Nuzzling me during feeding was mutually allowed, however. I never measured it, but I think the tongue of a cow is ~12" long, and she could stick it right down the back of my neck. That probably produced as amusing results as pinning me up against barn walls, for her. Cows are surprisingly playful.
Goodness I can imagine that she didn't do that again! And licking down the back of our neck! Ewww!! Ha! I always have in the back of my mind - Cows Gone Wild - like those commercials that used to come on TV - Dolphins Gone Wild or Sharks Gone Wild - where they attacked people. Ha! It's always good to keep their size into perspective. Even if they're gentle, they've got a lot of weight to throw around and accidents happen!
