Whoa, Uncle Pasha. Rock.
My family's horses get all po'd if you leave them behind in the pasture and take others out riding. The QH I had while I was growing up would actually come up and stick his head in bridle and grab the bit in his teeth if you'd stand in the field with it outstretched. If you've got a willing animal that's been trained up well and you treat it properly, they generally love to be ridden.
