How does the author use foreshadowing in Boys and Girls?

In a story about a young girl's feelings about being trapped into a position she is not looking forward to, the subplot concerning the two horses bought to be used for fodder is an instance of foreshadowing. Although any reader will understand that the success of the fox farm depends upon the sacrifice of these two animals, Munro's attention to Flora's attempt to run away nevertheless provokes feelings of pity for the animal whose life will end while it is in its prime. The inevitability and unpleasantness of this animal's fate foreshadows the fate of the girl protagonist. No matter how hard she tries to resist her future, she is destined to lose to forces greater than herself.
