Someone sneezes twice with a two second pause in between. How many times do you say "bless you"?
Twice usually unless I'm tired or distracted.
I don't even know why I say it at all. It is based on a superstition that a demon will possess you when you sneeze. It is thought that your heart stops or skips a beat when you sneeze, allowing a demon to possess you.
My Wife sneezes in full auto mode, so I say it only once when I think she is done.
I thought it dated back to the Black Plague. I do agree it is a useless and outdated saying. I only say it to be polite.
Me too. Too many people expect it. Black Plague may be correct. There are probably a few origin stories out there.
Zero? If either - once.
