We were just discussing my plans to get down there this month since there are issues with my Mom. Sis was telling me how glad she was to have her big sister flying down because I'm the family's "joan of arc" where my mother is concerned. (Mom's abusive) All of a sudden, I don't know anything. It was an amazing turnabout. I was brilliant and brave right up until Terri was mentioned.
That's kind of odd.
Is it guilt? shame? denial? all of the above? (no, I'm not saying your sister has personally done anything....however, she and others may not have personally done anything to help fix it; she and others may be responsible for electing certain of the senators/representatives who 1) voted in the people who got this law passed in the first place 2) didn't kick them out of office/re-elected them.
(not trying to make you feel bad about your sister....but, if this were happening in my state, and i could have done something about it (rallies, letter-writing to my elected officials/voting against them, etc.), and not do so, a natural reaction would be to be defensive, etc.)
