Why does only one nostril become clogged with mucus and not both simultaneously?

I've been sick all weekend and my sinuses have been stuffed the entire time, this is what I've been wondering...

By the way, it's a common misconception that stuffed nostrils are clogged with gunk.  It's actually the swelling of the tissues back there that closes off the airflow.  That's why, often, you can blow your nose until nothing more comes out, and you're still stuffed up.
