Actually I have an intense fear of horses IRL.
You see, there were a pair of horses at a stable next to my little brothers baseball field when I was younger. We think high school kids or some other fuckers were harassing them and they got mean. As in, see a full grown horse attempt to kill a 4 year old mean.
They wouldn't just try and attack people, they would wait for people to stop paying attention if they wandered to close to the fence and try to slowly walk over, bite them and toss them around.
I'm always extremely nervous around horses and they always pick up on it so all further interactions have been at best neutral. So yeah, I ain't gonna a real life horse.
