Let's see - she's a poor decision maker (just judging by this snippet of info I am privy to), doesn't think before she acts and isn't necessarily logical.
So, basically she's a woman.

That wasn't meant to bash women, it was simply meant to highlight the fact that men and women are wired ENTIRELY different and women do not always act as logical/rational as men do.

That wasn't meant to bash women either, it was simply meant to communicate the fact that you CANNOT attempt to understand/analyze something a woman does thru the typical man's eye or point of view. It just doesn't make sense.
It was a stupid, immature and irresponsible move on her part. Simple as that. If she was apologetic and realized it was not smart for several reasons (most importantly - it's effect on you) then let it slide.
If it happens again, then it's talkie talk time
