A 28 year old lady gets marries a 32 year old man.
She has a group of 4 friends, 2 are married, 2 are single.
The single friends are side chicks to married men.

The man tells his wife he's very uncomfortable with her friendship with such women.
It's immoral, he says...

The wife would have nothing of it.
"Stop judging my friends! You're not God! They're not under any obligation to live up to your morality standard!"

"You don't get it, do you?
It's not about THEM: it's about YOU. Associating with side chicks tells a lot about YOU!"
Hubby says...

Wifey couldn't be bothered.
"Just leave my friends alone: how they live their lives is not your business!"

Ok.

Husband let it go.
He never brings it up again.

About a year later, someone tells wifey she saw her husband having lunch with a young lady in a restaurant...

Wifey asks hubby who the young lady is.
"My side chick!"
Wifey is stunned!
What????
"My side chick!"
How dare you???
Hey! Don't judge me! I'm not under any obligation to live up to your morality standard, hubby submits.
You have no problems with your friends being side chicks...

Why should you have a problem with me having one?
You defend your side chick friends, why are you now upset at me?
Are you aware the men your friends are side chicks to have wives? How do you think they feel?
You are not concerned- until your husband now has a side chick!
