Women's intuition.
It's supposed to be dead on, isn't it? A fool-proof way to tell that when your boyfriend says "You look awesome in that dress", he really means "God... That's a bloody huge ass" or when your bestfriend asks "Are you full?", she really means "Are you anorexic?"

But sometimes, just sometimes, don't you just wish you might be mistaken? That for some reason, other than you not being a woman anymore, your supposedly all high and mighty women's intuition is wrong.

Because it can be terribly ironic when you know you are right but you have been wronged. Not only is it ironic, it's oxymoronic and just plain screwed up. It just kinda proves that being right isn't all that.
