We've all had the "It was a box with Error in it" conversation!
"The computer said it had an error, do you know what it is?"
"What error did it say it had?"
"It said 'Error, something something I did not read it then forgot' is that any help?"
"Yes, that's perfect, it means the fault lies between the keyboard and chair..."
