Example: line of T storms popping up west of Houston and moving towards the airport. The current TAF doesn't yet reflect this; however, one look at the radar does. We have no extra fuel (besides reserve) and no precautionary alternate. You make her aware of the situation and she gets nasty with you. The flight deck is now poisonous and the captain is incompetent. She wants to blast off with no plan B and unwilling to listen to any input. There is no 'big picture' with her. No 'out of the box' thinking. If it's not written in black and white right in front of her, she won't get it. This is just one example. I won't even go into her flying ability or landings.
