Apparently they were rescued horses and therapy horses. The organization was to have horses help with trauma. Apparently they are very good with people with PTSD.
It wasn't your fault, they also point them back when distress like kids being very loud. When I had Ranch camp last year, we couldn't tell or run around them
Also if you walk behind a horse and your close to its behind, you need to touch their backside so that they know your there and don't hit you in the stomach and break your ribs
