My friend sent this to me yesterday which blew my mind and then led to me learning far more about equines than I had ever really bothered to in almost 30 years (in fairness, I thought it was like a toddler horse).
I'm now scared about how many assumptions I have about the world that are wrong. (I will say, I think late 80's/90's cartoons could have done a better job because a lot of my friends weren't aware of this either)
