If you are wanting a rat all i have to say is get the money yourself somehowe
than get ahard drive for a slide show or just some pics
than i would meet the rat first or if u cant than just tell her u know what its like
than ask mommy verry niceley and get her things she wants
than say hey ive got money right then say ill do everything u want
and if she knows than she will maybe say no cuz they stink and that's when u say ill be there to deal with it
than if she doesn't know she might say what of what do u want than u say i want a rat i think that im responsible and ready through in sad face and say pweeeze mommy if that dosent work.....well make sure u are responsible work her for a few days and try again that's all i got
