How does Erma Bombeck use imagery in If Life Is a Bowl of Cherries, What Am I Doing in the Pits??

Imagery:

"There are no records to prove it, mind you, but I have every reason to believe my husband was an eleven-month baby. And he's been running two months late ever since."

"Now there are few things in this world more satisfying than having your son teach you how to play tennis. One is having a semitruck run over your foot."
