A boy asks his father to explain the differences between irritation, aggravation, and frustration.
His father picks up the phone and dials a number at random. When the phone is answered, he asks: “Can I speak to Alf, please?”
“No! There’s no one called Alf here,” says the person who answered the phone.
His father hangs up and says: “That’s irritation.”
He picks up the phone again, dials the same number, and asks for Alf a second time. “No, there’s no one here called Alf. Go away. If you call again I shall telephone the police,” the person says.
His father hangs up and says: “That’s aggravation.”
“Then what’s frustration?” asks his son. The father picks up the phone and dials the same number a third time.
“Hello, this is Alf. Have I received any phone calls?” he asks casually.
