How does Lorna Landvik use imagery in Angry Housewives Eating Bon Bons?

Imagery:

"When Merit told Eric that she was joining a book club, her husband had laughed out loud. Then, as if someone had abruptly turned a switch, his laughter stopped."

"When a cop grabs you up off the ground, your impulse is to scream and/or wet your pants. At least mine was. Instead, I looked to my fellow protestors for behavior guidelines."
