You and Phil play at AFL together, and despite training at the same place, you don't get along very well. Since your parents had to travel, and they're friends with Phil's, you had to stay at his house for a while. 

One day, you have an important game and as you're all living together, Phil's parents drag him to watch you play. To his surprise, you also played field hockey and at state level.

Phil was enchanted by your skills and began cheering for you, almost forgetting that you were enemies.
