Conscience
It's those moments when you inhale the air in a glass so that it sticks to your face while you thoughtfully stare against the blank, whitewashed wall opposite your computer desk as sunlight's neverending streams of light floods the room that makes a man…think. Think about life and unjustices. Think about the humanity of mankind. Like the glass, mankind is forever stuck to your chin until you exhale and mankind drops to the floor, shattered into fragments with a noise that daggers through the air.
But seriously, I like empty glasses.
