In Chapter 2, what are Larbi Amrani's thoughts about prayers beads on his rearview mirror?

Larbi Amrani has a string of prayers beads hanging on his rearview mirror. He worries that the way they broke is an omen. His mother gave him the beads when he graduated from college, shortly before she died. At first, he had carried them in his pocket and fingered them after every prayer. Eventually, they ended up decorating his car.
