'Everythings Fine'

I hate the word fine.  My girlfriend tells me everything is fine when clearly there is something bothering her.  Why can't women just tell us when we f%#$ up?  Like did I miss her birthday, or did something go wrong at her work?  I mean women are supposed to be emotional, yet when something is wrong... 'everythings fine'.  Guys if you ever hear your wife say 'everythings fine', it is the exact opposite, just some words of warning!  I guess I will be sleeping on the couch tonight.
