Missanna,
Very good response to your sister. She wanted your unsubstantiated (no proof sited) answers and you demanded same from her. Good girl! A friend of mine told me that I wanted proof JW's were wrong, but that I had no proof they were right. Wow! I wish you the best. I would try a snow job on dad and melt honey all over him while telling him your reasons. Dripping honey loaded love all over my dad always worked for me and made my dad respect my decisions. Burning bridges with ultimatums is kinda dangerous.
