I'd printed out 95/345 pages of my novel when I heard an ominous beep, beep, BEEP noise. I glanced at the printer.
"Out of yellow ink," it said.
I shrugged. "So what? I'm not printing my novel out in yellow I'm printing it out in black."
"No," said the printer. "I'm out of yellow ink. Replace the yellow cartridge and then, and only then, will I print out your novel in black."
"But that doesn't make sense. The black ink cartridge is full. It doesn't matter that the yellow one is empty because...YOU'RE NOT GOING TO USE IT."
"Don't care," said the printer. "I'm not going to print any more of your novel and that's that."
I feel an early morning ink cartridge shopping trip coming on. That's if I haven't kicked the printer to death first.
