I have a horse somewhat like that. He does not care for people petting on him and being all lovey-dovey. He would prefer someone put him to work so he can do his job, feed him, and then put him back in his pasture and leave him alone as a reward. Funny enough, the horse in my avatar is that horse. I promise you his ears were back to his head when I took that picture. Lol.
On the other hand, my barrel racing mare cannot stand it when people are around and don't pay attention to her. She will buck, roll, etc. just to get someone to pet her. I have to say, I really prefer a horse that prefers to be left alone, but I do give her all the attention that she desires.
