Explain how Amanda deceives herself in Scene 5 of The Glass Menagerie by Tennessee Williams.

Please submit only one question at a time.  (I had to
delete the second one that you can submit on another
post.)

In Scene 5 of The Glass
Menagerie, a drama about those who hide their disappointments in illusion,
Amanda joins Tom on the fire-escape landing, sitting upon a newspaper "as if she were
settling into a swing on a Mississippi veranda."  When Tom points out the moon, Amanda
speaks with Southern charm as she describes the moon as a "little silver slipper of a
moon."  She wishes upon the moon for success and happiness for her children.  And, when
Tom informs her that there will be a gentleman caller, Amanda is ecstatic; to reflect
the magnitude of Amanda's feelings, the stage directions read, "The
annunciation is celebrated with
music."

Immediately, Amanda plans what she must
do.  As she combs Tom's hair she asks about the young man who will come to dinner,
telling him "The last thing I want for my daughter's a boy who drinks!"  She then asks
about his job and his salary as though Laura is already betrothed. When Tom accuses her
of being premature, Amanda retorts,

"You are the only young man that I know of who
ignores the fact that the future become the present, the present the past, and the past
turns into everlasting regret if you don't plan for
it."

And, when Tom reminds
Amanda that Laura is crippled, she refuses to have her call her that, saying Laura is
strange in a good way.  Moreover, it seems more that Amanda is planning for herself, not
Laura.  She speaks of slippers as though Laura is Cinderella and her prince is coming. 
Deluding herself with elegant phrases reminiscent of the charming Old South and
pretending that the visitor is a gentleman caller for Laura when Tom has explained that
Jim is not aware that he is coming to meet Laura, Amanda acts as though she is still the
pampered Southern lady, not a single mother of a St. Louis
tenement.
