A doctor, a lawyer and a programmer were discussing if it’s better to have a wife or a girlfriend.
Lawyer:
"A girlfriend is better. If you divorce your wife, that’s causing a lot of problems."
Doctor:
"A wife is better. That’s secure so you don’t have to worry so much."
Programmer:
"You need both. When the wife thinks you’re with your girlfriend and your girlfriend thinks you’re with your wife – then no one disturbs you while programming."
