Hal's signature explosive sneeze

Why do I sneeze at least once every weekday during my campus job shift from 2-5 pm? It's embarrassing. This has been going on for over a year. I am not sick. I don't sneeze other places in such a constant manner. And why can't I make my sneezes quiet? I have man sneezes. Sounds like I am an elephant, spurting out gallons of water. I am practicing quieter sneezes, then it just gets out of hand. How can I sneeze quietly? I think I am allergic to work. yep. I quit.
