Dear Guy coughing up a lung in the Cube next to me,
GO HOME! I don't care if your doctor said you're no longer contagious, you sound awful and that in itself is distracting. You have sick leave, use it. Please.
May I also suggest that you suck on throat lozenges, or drink some throat-coat tea? There's a reason I tried to give you a bag of lozenges yesterday.

Your cube neighbor, who hopes you get to feeling better soon.
