I ALWAYS say "bless you" when I hear someone sneeze. I could be in the supermarket or walking down the street, it doesn't matter. People are always surprised to hear a stranger bless them soon after they have sneezed. I have always enjoyed their reaction. I think it is just plain polite to do so.
So, we started a new little thing a few months ago.
Someone sneezes...WE ALL SAY BLESS YOU!
It's very cute when Baby S sneezes and seven people are blessing her from across the room.
Just another little lesson in the Manners Department.
