What is the flashback in "Blues Ain't No Mockin Bird"?Toni Cade Bambara's "Blues Ain't No Mockin Bird"

Flashback is an interruption in the chronological order of
a narrative to describe an event that happened earlier.  A flashback gives readers
information that may help explain the main events of the story. Usually flashbacks occur
with a character who is the narrator in the story; however, in Bambara's "Blues Ain't No
Mockin Bird" the flashback is narrated by Granny rather than the young girl who narrates
the rest of the story.

Annoyed by the two men who appear in
her yard with cameras, filming their home and possessions, Granny recalls a memory of
having been on a bridge where a man was going to jump.  A crowd formed, watching the man
and a minister and a policeman who tried to talk the man out of committing suicide.  His
woman was nearby, biting into her hand in nervousness.  And, while the man was ready to
jump and the two other men talked to the man while his woman stood nervously by, there
was a person with a camera, Granny says,

"taking pictures of the man in his misery about
to jump, cause life so bad.  This person takin up the whole roll of film practically. 
But savin a few, of
course."

This flashback, of
course, reveals much about Granny and her reactions to the men with the camera who are
on her property.  To Granny, like the person on the bridge, these men have no respect
for the private actions of others, and merely want the opportunity to sensationalize
life and sell their pictures.  In short, Granny finds the men with the camera
despicable; she has no tolerance for their patronizing behavior towards her and her
family.
