Jamie asked his dad to explain the difference between irritation, aggravation, and frustration. His father picked up the phone and dialed a number at random. When the phone was answered, he asked, "Can I speak to Rolf, please?"
"No! There's no one named Rolf here," replies the person who answered the phone.
The father hung up. "That, my boy, is irritation." He picked up the phone again, dialed the same number, then asked for Rolf a second time. "No, there's no one here called Rolf. Go away. If you call again I'm calling the cops," the person said. The father hung up and said, "That's aggravation."
"Then what's frustration?" asked Jamie.
The father picked up the phone and dialed the same number a third time. "Hello, this is Rolf. Have I received any phone calls?"
