After reading about the family that made their young disrespectful daughter stand with that sign on a street corner, I say “bravo” to those parents. They should stop worrying about what someone else says.
She is their daughter, not someone else's, and what the public thinks should be of no concern to you.
This is exactly what is wrong with the rest of the country today. Our children have no respect for anything, including their parents.
Good luck to you, the parents.
