It is difficult to understand why BD replies to things differently than would be "normal" but if you look at her personality type she is an overview person. She doesn't concentrate on details about everything in life. There are overview people and detail people. Obviously most of us who like to analyze things are detail people. If I speak to someone I'm curious about all the details. I could tell you exactly what was said, what was worn, the weather outside, the time of day etc. I live in details. I know many people who are overview. They don't ask questions, they don't retain details because their mind never focuses on them. They think in a very different way than detail people. So when we analyze BD she is a true overview person. She can't remember most things because she doesn't concentrate on them. Many overview people don't express themselves well, don't give answers to questions without multiple ways of asking. Just think about the people we know and you will be able to put people in either catagory. I don't believe BD did anything to HD nor do I believe she knows what happened. SD is a manipulator that is why he is attracted to BD and he has done many, many things in the relationship that BD would never have noticed. Manipulators walk all over overview people. BD's plea on NG last night about HD calling 911 was an attempt to do what MK wanted her to do. She looked away because she was going to start crying, it was a natural way to shut down for a second to gather herself, so that she could not cry. I don't believe she is guilty at all.
