My only, or greatest, problem with other people's flatulence is that if I detect something, which emanated from your person, one could surmise that an unpleasant and ejected element, even if only a molecule, that was just in your rectum is now setting up shop in me. And, in an OCD guy's mind, you might as well pick me up and insert me, head first in an ally mcbeal like antic, into these vaporous confines that jettisoned this waste product in my direction.
