"divide and conquer method" also known as shopping around for a different answere. LOL at times you need to become a real lawyer about it:
"I see, now before ansereing your questions, have you at any time now on in the past aksed you mother this question, in whole or any part there of, either directly or infered and has she rulled on this matter?
Regardless of how I may respond to your request, understand that any and all proclomations, decisions and or threats previously stated or implied by your mother still stand and, my answere to your question not withstanding, her prior ruling willl infact be inforced.
Oh and the penalty for fraud is triple damages."
