The Way Smoke Smells

So I really love going into the conference room at this day job, and I just realized why. Everyone who smokes goes through the conference room and into the fire escape, and so there's a residue, not of smoke, but of sort of pre-smoke and post-smoke, maybe the smell ignited by freshly burning paper, or a special smell that only happens at the moment when a match strikes?

It reminds me of my aunt's house growing up, and of inch-high shag carpeting, and of the '70s. No word on whether there's a bunch of furtive, antisocial Siamese cats patrolling around the office, but I'll keep you updated.
