For the last two Sundays I took her with me to church, and she behaved like a two year old before we left (mostly regarding what she was going to wear) but when we got there I doubt most of my church friends even noticed she had any kind of a problem! She was suddenly able to "put on" what I call the "bed and breakfast owner" personality and was all smiles, friendly, and talking with my church friends. Then, almost the minute we got home, the provocatively hostile behavior started all over again, with her acting like nothing could keep her from arguing about SOMETHING, no matter what! No matter what I said, she was able to turn it into an unending argument. It almost seemed like she knew she could drive ME crazy, but I saw that she also knew darn well when to "behave". Is that common? It makes it seem like they're more aware of what's really going on than you might think, and that a lot of their behavior may be more deliberate than simply a manifestation of the disease.
