Cup: Represents how deep life is.
Coffee: Shows how dark life can be.
Spoon: Represents the manner how we dip into things we're not supposed to.
Cream: Shows that we try to artificially lighten what should remain dark.
....and of course we always make a big mess. Tha coffee overflows the cup and drips down. And we always try to cover it up. with a napkin but we know that all the messes will just soak through.
