Me: “How can I help you?”

Customer: “I can’t do that thingy.”

Me: “I’m sorry, What thingy?”

Customer: “Emails. It keeps saying error 421. I never put that number in.”

Me: “That’s an error number. Can you tell me what lights are flashing on the modem?”

Customer: “What’s that?”

Me: “It’s a small box with cables running into it. It will have a lot of lights flickering on it.”

Customer: “The box with the blinky lights?”

Me: “Yes, that should be it.”

Customer: “Oh, I thought my son put that in here to annoy me, so I unplugged it!”
