About Annie Dillard's Chase

The story tells an event that Annie Dillard had lived when she was a young child. In the story Annie and her friends throw snowballs to the car's that pass in front of them. While they throw, one of the cars stops and the driver gets out; he starts chasing Annie and her friend Mikey. At the end of the story when the man catches them he only tells one sentence to them and lets them go. 

At the end the author was shocked and happy at the same time. She learnt that the glory can't last forever since the man caught them. 

In the story she says "But how could the glory lasted forever?"  We can see the lesson she learnt from this question that she asked. In the story the glory of the chase doesn't last forever so I think that this question can be a good quote to show what she has learnt.
