"You bully Lily every day at home, and now you're going to do the same thing at school? I'm warning you, if you dare to bully Lily in the future, we won't let you off!"
Laura pointed at herself in disbelief and laughed, "You mean, I bullied Lily?" Laura recalled the girl's name and pronounced it, "Joy?"
"Of course! Lily told me all about it ..."
"No, don't say it." Lily covered Joy's mouth with a flustered face. Her voice was low and weak, "My sister didn't bully me. She's always been good to me. How could she bully me." Only, this faint explanation sounded like a lie on her aggrieved face.
The crowd became more and more convinced that Joy was telling the truth and looked at Laura with disgust - this was a disgusting and vicious way for an illegitimate daughter to bully a real one behind her back! Poor Lily was bullied like this, but she still cared about her sister's reputation and was not willing to expose Laura's malignance.
