The adventures of Trefor the curling rock

Trefor the curling rock spends his nights staring through a crack in the door whispering, "I wish and I wonder about things I cant see, I long for adventure to know what else I could be. Am I simply a rock destined only to curl? I know theres more out there, I want to see the world." Eventually curiosity gets the better of him and he sets off on an adventure to try his hand at tennis, hockey, and diving. Will Trefor leave curling behind forever or will he realize its the only sport for him?
