You exhale somewhat forcefully though your nose and involuntarily expel a blob of plegm from your nostril. You know it's out there somewhere, but you don't see where it landed. You are afraid that you'll be talking to someone, maybe someone important, and you'll notice they are staring at something on your sleeve or your tie or something. So you have to stop everything and find that phantom blob. Or maybe it lands on the steering wheel and you put your hand in it. It's a bad thing. Just sayin'...
PS - I'm really just trying to get the tsunami thread to page 2 as quickly as possible.
