What type of irony is there in the story?"Blues Ain't No Mockin Bird"

When the men with the cameras take pictures near the
Cains's place, Granny exhibits several times verbal irony in her speech. With verbal
irony being the saying of one thing when actually something else is meant, Granny
certainly provides several verbally ironic statements in the beginning of the story,
"Blues Ain't No Mockin Bird."

• One instance of
  Granny's verbal irony occurs when she tells the children to "Go tell that man we ain't a
  bunch of trees."  Her meaning, of course, is that she does not want the men taking
  pictures of them as though they are inanimate, or treating them as
  such.


• When the men approach and one says, "We thought
  we'd get a shot or two of the house and everything and then--"  Granny cuts him off with
  "Good mornin," with her tone indicating anything but friendliness. 
  


• As the men ask to take pictures, they seek to ingratiate
  themselves by saying "Nice things here" as he buzzes his camera over the yard; however,
  with irony, Granny retorts, "I don't know about the thing, the it, and the
  stuff."


• Then, when one man calls her "aunty," she again
  replies with irony, " I don't know about the thing, the it, and the stuff,...Just people
  here is what I tend to consider."  Here the implication is that she resents the men
  filming their yard as though what they possess is something to be regarded as a
  curiousity--"stuff" to be laughed at or scorned or
  mocked.


• Granny relates the sad tale of a man who
  contemplates suicide while a person callously films the agonizing moments as the man's
  woman stands by, and the minister and the policeman try to talk with him. About the
  person filming Granny comments, "This person takin up the whole roll of film
  practically.  But savin a few, of course."  Granny really means that the person is so
  cruel that he/she saves film in case the person jumps, so this tragic moment can also be
  recorded.  (After all, that footage will sell.)


• Finally,
  when Granny calls to Mister Cain to "get them persons out of my flower bed..." she means
  instead to get the camera men off the
  property.

In her essay, Black Women
Writers, Ruth Elizabeth Burks writes that Bambara considers the limits of
language to convey independence.  Clearly, with her verbal irony, Granny conveys her
fierce independence and desire for privacy in "Blues Ain't No Mockin
Bird."
