I still try to figure out, what did Michael mean when he told Kay, there have been things going on between men and women? (When they are in the hotel and Kay says she is leaving)Was it that men have their business and their wives don't need to know? Or was he referring to her being depressed over what he thought was a miscarriage?

I always thought he meant the first one.. that a woman doesn't need to know her husband's business and should basically do what she's told without question.

Personally...I've always thought it to be an improvised line of Pacino's. When listening to that little bit of dialogue with Michael & Kay yelling over each other as we watch the children in the hallway - I get the sense that much of it is unscripted & FFC instructed them to just go at it.

Anyway the overall point of the line is:

"Yeah, yeah, yeah...you're unhappy, so what, happens in plenty of marriages, doesn't matter, I'm too busy to talk about it, you're staying, nothing changes, case closed, now can I PLEASE get back to my work."

ps - and by the way, why does this question show up TWICE in the same forum?

Dunno - it was just showed up twice? I think just internet error
