Girl in my cl and talking back?

A child who has come out of an abusive situation, who has a sibling still in the abusive home, needs to be treated gently. That doesn't mean letting her get away with being disrespectful, next time don't let the situation escalate, if she needs to speak with someone during a time when students aren't allowed to leave the area they are in, direct her to the principal, someone kids should always be allowed to speak with.
