@abc7chicago: An equestrian on a ride by the sea in Rome with a friend was startled when her friend’s horse, Parko, suddenly bit the mane of her mount. Sara Giacomini was filming her friend picking up Parko’s excrement as the group was stopped in Ostia. Parko takes advantage of the pause to engage in a little horseplay, grabbing the mane of Giacomini’s horse in his teeth. Giacomini can be heard laughing and shouting, “No, no, Parko, let go!” in Italian. Giacomini told Storyful the two horses are friends, and that they were playing.
