I don't know where I heard it, but years ago someone told me that when you have a sneeze stuck in your nose, that if you look at a light it will help the sneeze to come out- or in some cases go away.
I have no idea what the science behind that theory is, but for me it works. Only, today I am a snotty drippy mess in the middle of the library trying to cling to any time I can spend away from home and on the Internet.
It seems every time I look at a light, I sneeze, then ooze, then run to the bathroom to blow my nose. I can barely see to type because my eyes are running like leaky showers. At some point it would just be easier to go home, curl up with my box of Puffs con Lotion and watch a movie.
