The meaning that any event has depends upon the «frame» in which we perceive it. When we change the frame, we change the meaning. Having two wild horses is a good thing until it is seen in the context of the son's broken leg. The broken leg seems to be bad in the context of peaceful village life; but in the context of conscription and war, it suddenly becomes good.
This is called reframing: changing the frame in which a person perceives events in order to change the meaning. When the meaning changes, the person's responses and behaviors also change.
