have you ever thought of calling your Grandma and telling her? it would be best if you did it when moms out of the house (that is if she ever does leave the house) then ask gramma to talk to your mom, that should whip her into shape and if that doesnt work then you have you just have to talk to your mom i've confronted my mother about stupid s**t she does and i usually end up getting hit or something then the next day or so the stupid s**t she does usually stops but at least its worth it
