As a youth, my buddies and I (the little bastards that we were) would walk right through small herds of cows as we passed through various fields to go fishing, exploring and whatever. They looked up, then went back to eating. Always wary of bulls though, of which we would occasionally test their temperament by peppering them with rocks once we were at a safe distance. Small rocks, mind you, we didn’t want to cause pain, just get a reaction.
