When other people sneeze around me at work, I'm pretty good at saying something like "God bless you" or "Gesundheit".  As a small aside, it seems to be a common misconception that Gesundheit is German for "God bless you".  This is not true.  It literally translates to "health".  So when you say Gesundheit to someone after they sneeze, you're wishing them good health.

Anyway... back to the topic at hand.  After I sneeze, you could hear crickets.  Nothing.  No "God bless you".  No "Gesundheit", not even a "You're so good looking."  What gives?  It's almost enough to make a nice person like me stop saying it to other people.
