I totally agree with you. I was trying to be polite. My friend had just introduced me to the owner that day. So I had no previous knowledge of what her experience was with her gelding. I am 28 and the owner is in her 60's, so as a matter of absolute respect, if she told me I needed to sing Twinkle Twinkle Little Star to her horse because that's what he likes, then I would likely oblige. So when she asked me to hand him over so she could get on, I did exactly that. Knowing full well that she seemed apprehensive and nervous with him.
I have since sopken with my friend about what happened that day. I also offered tp help this owner find some great alternative options for her gelding, and to help her in finding a more appropriate choice of horse. I am under the impression that she wants to keep him, but maybe just as a pet. And while I may not agree with this deicsion, I am thankful that the likelihood of her being injured by him is now significantly lower.
