An old man calls his son:”Listen, your mother & I are getting divorced. 45 years of misery is enough."

"Dad, what are you talking about?"

“We can't stand each other, I'm sick of her so call your sister & tell her.”

The son calls his sister. She says, "Like hell they’re getting divorced!" & calls her father. "You’re not getting divorced! Don't do anything, we are flying home tomorrow to talk about this.”

The old man turns to his wife "Okay, they’re coming for Xmas & paying their own airfares."
