Obviously I am not murderous, but the urge so say something inappropriate is unbelievable. The sound of the chewing makes me want to scream, and then I fixate on it because I become so aware of how much it hurts my brain. I want to complain, but you can't tell your supervisor a coworker's imminent heart attack is bothersome. Maybe he will actually die on the job and I will get a legendary FPH post from it. Silver linings and all that.
