Does the title "A Rose for Emily" suggest something about the author's message?

William Faulkner's title definitely connects with the
theme of the story.  If you think about it, imagine circumstances when people are given
roses.  Usually, it is a formal occasion where the rose is given to symbolize honor,
respect, affection, or to make the person feel special or acknowledged.  Also, roses are
a noble flower, the top of the line in elegance and
beauty.

Now, keep that in mind as I describe the next
scenario.  Emily's family came from a time where their wealth and name meant nobility
and earned respect from the townspeople.  They were like the royalty of the town; they
were the top of the line.  People revered them, and their wealth and position bought
them special privileges.  They recieved tributes and honor from their position.  All of
this ties to the rose--when WE meet Emily, that honor, respect and royalty has faded
away, and all that is left is the crumbling remains of the legacy that was once her
family.  No longer does she get the "rose of respect" or tokens of honor and affection
from the town.

Faulkner uses the rose in the title to
symbolize the decline of Emily's status; the story is a tribute to her faded legacy.  It
is her last hurrah, a last record of the last of a dying family wealth and reputation. 
The last rose offered on her behalf.  I hope that those thoughts helped; good
luck!
