After you get off of a horse you stand on the right side of it. In real life you will NEVER get off a horse on the right side but always on the left. The reason for this comes from the era of knights. They always had their sword on the left side so it was easier for them to get up and down a horse on the left side. Since Minecraft values real life references very highly, I want you to know this

When I get off of a horse I stand on the left side.

What actually happened was...:
