I had a horse... one of those "I didn't mean to acquire him" types... one of those the hoarding breeder got out of control and ran out of money with a bunch of malnourished pregnant mares... one of those orphaned colts as a consequence. I tried to say no... but Pico wound up with me. He was Curious. Not the most confident nor athletic with his clubbed foot, but he sure did keep everyone entertained.
While doing so, the herd had galloped over as they took their job seriously as the official Greeting Crew. All except one horse stopped about 50' away from the trailer. Pico, ever the curious horse, decided he would go above and beyond normal welcoming duties, and climbed into the client's trailer to escort the new arrival.
