When I was little, I was under the impression that smells of things were actual little particles of the things floating through the air, and then getting caught up in your nose and triggering the sense.
For some smells, this seems reasonable. Especially stuff like smoke or a perfume spritz, where you can actually see the thing you're smelling. The idea is acceptable enough when smelling coffee, but can be particularly disconcerting when smelling someone else's fart.
Fortunately I have an engiineer friend who straightened me out. Smells are actually certain chemical elements which emanate from the object. I dunno. Still doesn't make me feel that much better.
But this all reminds me of a story which I will blatantly steal.
A couple Carol knows were at a party. They are generally a very fun couple, but this particular night wasn't a good one, and they knew few people, so they decided to sit in the corner alone and just get hammered.
The plan was going swimmingly, and the couple was having a grand old time in the corner. But the party was beginning to pick up, and occasionally, others would come and intrude/interrupt the couple in the corner. After all, it *was* a party. In one lull between intrusions, the lady farted. A good one. Sulfur like an old egg sandwich mixed with a touch of hell.
Did I mention this was a work party? I didn't? Well, maybe I'm making that part up for dramatic effect. So anyways, the boss chooses this particular moment to head over to make a visit.
"Hurry up and inhale," demands the wife.
"What?" the husband asks.
"I just farted and I need you to help me inhale all the fart up."
So the two sat in the corner, drunk as skunks and breathing as deeply as possible in order to inhale all the possible fart particles out of the air before the boss got there.
See? I'm not the only one who believes in fart particles.
