Depends on what I'm smoking. If it's an aero that the fiancé thinks smells nice, I'll smoke in my den/office/homework destruction area.
If it's a bold, flavorful, maybe heavy Lat type blend that the fiancé hates the smell of, then I will smoke in the den/office/homework destruction area...with the fan on. :

I will soon invest in a Lampe Berger, though, as the brilliant ventilation dynamics I have engineered probably aren't the best way towards longer term post pipe smell.
