Unsupportive Wives

Chris and I noticed that there are SO many movies where husbands/boyfriends have a very important job, and when there is an emergency or a reason that they have to work late or go work, the wives throw a fit and either leave the man or give him shit when he gets home. It happens no matter HOW bad the situation really is. Why is that? I know it wouldn't happen in real life, but when they portray women like that in movies, they make us look like total bitches!

Example:

Wife: I really wish you wouldn't go and stay home and have dinner with your family.

Husband: Honey, there is a tremendous fire downtown and people really need all the help they can get right now.

Wife: But John, you NEVER spend any time with us. You're always at work and never have any spare time (nag nag nag)

Husband: Susan, I can't talk about this right now, I have a serious fire I need to go to!!!

Wife: You never listen to me, you don't care about me!

Husband: (very serious) Honey, I need to go. (leaves and closes the door)

(hours later the husband comes home, totally worn out, ashes all over his face, coughing up a lung from smoke inhalation)

Husband: Honey, I'm home!

(silence)
(He looks around the house for her, and she's not there, and he notices the closet was open and her clothes and things are gone. Then he finds a note that explains she has left him)

See what I mean? How many times do you see that in movies... especially dramas and actions? Women aren't really that stupid are they? I hope not.
