How Not to Treat a Blind Child

My daughter may get stares from children.  For the most part I can tolerate it.  Of course, their parents should teach them that is rude to do.  They other day, I went into a store.  Once entering, we ran into one of the employees.  She stood there and just stared at my daughter.  I wanted to ask if she had a problem.  It was downright rude of her.  If you come upon a blind person, don't sit and stare at them.  They can not help the way they are.  She was born that way.
