He learns that he is nothing but a mere vessel to contain the importance of life; the bees. These bees thrive off of the the marrow in his skull, the coils of his brain hold the precious hexagons of their honeycombs. The thousands of bees that lay dormant in there often wake at night, swarming and buzzing. The man's brain rattles with the sound, the pressure building up against his temple as the bees continue working through the night to create more honey. Oh god the honey, it leaks from his mouth, from all orifices, he can't make it stop and man is it sticky. His clothes are soaked with it, his face is coated with it, no matter how many showers or how many doctors, he cannot rid himself of this honey layer or these bees.
