How does Heather Hepler use imagery in The Cupcake Queen?

Imagery:

“[...] I think about the problem with running from your trouble . The problem is in the stopping. The whole time you think you're getting away from everything, the trouble is running like mad, too, trying to catch up with you. And it doesn't slow down when you do--it keeps on sprinting. So when trouble finally reaches you, it hits you hard
(p107)”
