Will somebody please explain to me what is a summary for Chapters 21-22 in Belle Prater's Boy?It doesn't have to be a summary, but just explain...

Woodrow convinces Gypsy to come with him on an adventure;
they will go with Blind Benny on his rounds. Benny shows the children his new shoes,
which the "boys at the hardware" store got him, explaining that the boys are like
family, and that he has Gypsy's parents to thank for that. Benny was born blind, and his
parents died when he was only twelve. To support himself, he became a "sin eater," which
is someone who takes the sins of dead upon himself by eating a banquet placed on the
deceased's casket, so that he or she can "go to...glory clean and free." Benny did this
for fifteen years, and was shunned by the townspeople because of it, until he met
Gypsy's dad, who told him the sin eater concept was "a bunch of ignorant superstitious
nonsense." Gypsy's dad brought Benny with him to Coal Station, Virginia, where he was
opening a hardware store. He gave the blind man a permanent place to stay, enabling him
to start a new life. Benny, Gypsy, and Woodrow sing and tell jokes as Benny gathers
things people have left for him outside their houses, and when they finally return home,
Gypsy realizes the joy that arises when people are good to others. She looks at Benny
and Woodrow through eyes of love, and recongizes that this has been one of the happiest
nights of her life (Chapter 21).

At Granny's birthday
dinner, Woodrow reads an essay defending his belief

"that Blind Benny, even with his poor sightless
eyes, is the only person (he) knows who can see with perfect clarity...because Benny is
able to see beyond
appearances."

Porter proposes
a special toast to Granny, then announces that the towns folks think it is time for
Gypsy to have her own formal piano recital. Although Gypsy is at first stunned, she
feels "a thrill of excitement beginning to grow." Doc Dot then makes a second
announcement, concerning Woodrow. She has a doctor friend in Baltimore, who has agreed
to see if something can be done about Woodrow's eyes; the chances of a successful
operation appear to be promising. Now it is Woodrow's turn to be elated, and Gypsy calls
the party "by far the best one (they) ever had" (Chapter 22).
