Valentine's Day Special Joke

An eldery man in phoenix calls his son in New York and says,i hate to ruin your day,but i have to tell you that your mother and i are divorcing,forty five years of misery is enough.
Pop,what are you talking about? the son screams.
:We can not stand the sight of each other any longer:,the old man says."We are sick of each other,and i am sick of talking about this.So,you call your sister in Chicago and tell her" and  he hangs up.
The son call his sister,who explodes on the phone.
"They are not getting divorced if i have anything to do about it".She shouts," I'll take care of this".
She calls phoenix immediately,and screams at the old man,"You are not getting divorced.Do not do a thing until i get there.I am calling my brother back,and we'll both be there tomorrow.Until then,don't do a thing,do you hear me?".and hangs up.
The old man hangs up his phone and turns to his wife.
Ok,They are coming for thankgiving and paying their own fares.
