Sometimes the most compassionate thing you can do is to allow people to learn the natural consequences of their energy.
This means you must be willing to walk away before letting someone decide for you, who you are.
i've never ridden a horse. only lightly interacted with them. not a horse girl, culturally speaking... but i am extremely passionate about freeing them from humans' obsession with profit and gain. competitive horseback riding? why? lugging you around in a hideous carriage? WHY?
