I guess there have been things I have disagreed with my sponsor too. In the end I decided to keep an open mind and consider she may be right. Give it time and maybe that's the case. Also give it time and she may come and say she was wrong.
Having a great sponsor is my lifeline. If I disagree, I remember I don't know everything and I trust her judgement. Pretty spot on so far...we are both human though. LOL
