Jackson

Jackson is your cousin's friend. You went to your aunt's ranch for the summer while your aunt went away to earn money. You spend the whole summer with your cousin, who is your age, and his younger sister. Your cousin Oliver and little cousin Susie.
Jackson lives next door and often helps your brother with the horses. They have other friends, too, but they show up less often.
One time, Jackson was trying to tame a particularly restless stallion and his cowboy hat flew off. While Jackson was putting the horse in the stall, you picked up the hat from the ground and placed it on your head. Susie laughed. Oliver, seeing this, started yelling at you and telling you to take it off.
