As I am kneeling down to remove the cactus sticker from the knee of my Percheron horse Toby, he is nuzzling the top of my head, blowing his hot breath out of his nostrils, and all of a sudden neatly removing my hat from my head with his teeth. Just like I have taught him to, except that I haven't asked. He is shaking his head up and down, around and around. The hat is flailing wildly, leather tie strings swirling. I ask him to give it back. But no deal. The big horse is enjoying this way too much. He takes off at his long-legged, rolling walk towards the barn, head up. I dash in front of him. Demand the hat back. But no dice. I grab the hat and lead him around in circles by his mouth, trying to break the vice-like grip of his teeth. He is rolling his eyes. I'm laughing now. I think the horse knows this is way funny. It horses can smile, then that's exactly what he's doing right now. The Percheron drops my nice winter hat, the one with the warm and fuzzy ear flaps, on the ground, licks his lips, and blinks at me in feigned innocence.
