Quoted from geminisue

If there willing to read what you present to them and if they feel free to ask you questions and you answer to the best of your ability, there is no more you can do.  Each person has the right to make their own choices, and we can't feel guilty, if we feel they made the wrong one.

Maybe you can use a bargaining technique with your dad, such as give BTD 6 weeks and if you see improvement please continue it, I love you and I want you in my life, forever, if possible!

Quoted from Shane

I convinced them today!!  Yeah!    I told them that Type O's tend to be allergic to penicillin and sulfa, and tend to be anemic...my mother is anemic a lot, and my father and I are allergic to both sulfa and PCN...my mother said "Ok, I'm sold...where can I find the books?"
