What is the moral of the short story, "The Piece of String"?What is the messages it gives?

Guy de Maupassant's short story, "The Piece of String," reminds
me of a famous misquote from Shakespeare's Hamlet: "Methinks thou doth
protest too much." (Actually, the quotation is "The lady doth protest too much, methinks.")
Either way, such is the case with Hauchecorne. Had Hauchecorne not continually tried to convince
the people of his village of his innocence, the affair of the missing wallet and the piece of
string would have eventually been forgotten. But because Hauchecorne persisted with his story,
albeit true, people just assumed that he was guilty of recovering and returning the wallet. Like
the premise of de Maupassant's famed short story, "The Necklace," "The Piece of String" has a
similar message: how a seemingly small thing can create the ruin of a
person.
