It's been a few years. But, about 2 hours ago, I watched the neighbors struggling for 20 minutes trying to catch their horse that got out. The horse wouldn't let them near it. On the 2nd attempt, I walked up, patted it on its hind quarters a few times, reassured it, and walked right up and grabbed the halter. Neighbors came over to get it and it started rearing up; so I ended up just walking it back to its pasture myself.
I also said to the neighbors, "the horse says it wants a salt block, it doesn't have one, does it?" "Nope." Horse whisperer too, though to me, it was pretty obvious from the horse's behavior what it wanted.
