I'm sorry you are in such pain, Lar. Parents have a way of triggering our emotions, no matter how old we are. I'm not surprised your parents memories are inaccurate. No two people perceive an event the same way, but mothers are notorious revisionist historians. My mother almost always recounts family stories the way she would like them to be, not how they were.

It sounds like you and your sister have a good, supportive relationship. Don't forget to take care of yourselves.
