I hunted a place where I had to cross a large pasture that had a lone horse in it. I shared an apple with that horse one evening. The next morning that horse came running up and nosed me in the back, knocking me down. I got up thinking I was in for a fight, but no the old gal just wanted to say 'howdy'. Later that morning I shared another apple before i crossed the pasture, she kept nudging me. I found a handy high spot and jumped on her back expecting to get buck off. She walked me to my car. After that, I shared an apple with her and rode across the pasture, over a half mile, she hung around until I was going back and she would take me back to my car. I think horses get lonesome when left alone too much.
