Food from the Mouth

Ay, ay, time for a new silly game you've come up with. You're sick, very sick. Identifying bits of chewed food, as coming out of whose mouth. You go wash your hands and rinse your mouth, but refuse to leave, because suddenly you have the urge to see what this complete stranger is going to spit out of his mouth. And you wait for the bits of food from his mouth to land on the sink and float with the water towards the sink beneath your tap. Pleasure. Strange.
