There’s something badly wrong with this picture…

I’ll give you a hint. It’s not the lack of colour — I’m just stuffing around with dark tones, something that’ll no doubt annoy the more photographically wise of my friends.
It’s not the chip in far side of the cup. That’s just additional character for a coffee cup, really.
It’s not even the strange mystical language written on the inside of the cup. That’s so cute. It’s almost like a real language!
No, the problem’s far more profound.
My coffee cup. IS EMPTY!
How could you let that happen?
