could you report it to the school or someone else that shes doing that? I've heard of schools allowing kids from other areas as long as there is enough room but to flat out lie about the address is messed up. what if no one picked him up a d someone trying to be helpful delivered him to the fake address. or what if the school was mailing confidential information. the poor kid obviously needs discipline and structure but where did he pick up the behavior to begin with? I hate to say it but if he thinks its ok to talk to your sil that way he probably saw someone else treat her that way. how does your brother (?) treat her behind closed doors?
