My brother and I are 20 and 24, yet when we go visit she starts yelling and screaming whenever she feels she is being proven wrong or "put in her place" when that is NEVER the case. We could just be having a simple conversation and she start up out of nowhere. She has told us countless times (verbatim): I don't HAVE to respect you, under ANY circumstances; I do it out of the kindness of my heart, but YOU DO have to respect ME! She has only apologized to me once, and that was when she was irrefutably out of line and had no possible way of justifying it.
