Maybe she was too impressed with herself. She sounded very narcissistic.
OMG!!! She refused to attend our wedding (for which I was grateful as I matured knowing the hell she’d have caused for us that day).
That said, my father had gone to her house to try to convince her to go. When he returned I asked what he thought of her and he said, “She’s extremely immature, and VERY impressed with herself.” LOL. How’s that?
