The document summarizes the narrator's first experience jumping on a horse. They arrived at their neighbor's farm and spent an hour practicing trotting around tires with their instructor Meg. Once Meg was satisfied with their positioning and the horse's response, she set up a jump with five poles leading up to it. On their third pass, the narrator rose in the saddle as the horse jumped over the poles. After landing successfully, the instructor congratulated the narrator, who was thrilled by their first successful jump.
