I had a friend who couldn't stop sneezing for several minutes after she sneezed once.

If I understood it right, it means that if you sneeze once, someone is praising you, if you sneeze twice, someone is censoring you (talking bad about you behind your back?) and if you sneeze thrice, then you have a cold or...laughing illness?
Actually I wasn't going for any sort of expectation. I merely typed up what has been my experience.. but I do appreciate the humorous spin you put on it..
I was laughing so hard I actually fell outa my chair..
