People who say "bless you" when someone sneezes. Why? I'm not religious and I'm fairly sure you aren't either. Even if you are, I highly doubt that you believe I'm expelling a demon or whatever gibberish it was that inspired the whole stupid freaking ritual in the first place. Why do you acknowledge sneezes and not other bodily emissions? Why does my sneeze trigger some kind of warmhearted pseudo-Christian pavlovian response but not my coughs and farts?
