Do you ever tell someone "bless you", after they sneeze?

When I say it, people get offended. When I don't say it, people get offended. It's very annoying.

No, I say "Gesundheit".
But I never know when it's appropriate. Do I say it if I don't know the person? Do I say it to distinguished people?

And more importantly: If they sneeze again did I fail?

Well I just think it's polite to say bless you. Many people may not know this, but the saying "bless you" after people sneeze actually came from the plague that broke out in London in 1665. Because whenever they saw/heard people sneeze, they would assume they had the plague, so they would give them their blessing.

I say Alhamdulillah!! in Arabic and it means God bless you..
but I don't say it because I usually don't remember... its a good thing to say by the way..

I let their husband say it first

I always thought it was "fuck you".

OMG NEVER EVER EVER. I made a poll a while back asking if it's normal to never say bless you, because in no way does a person naturally expelling unwanted objects from their nasal passages warrant a blessing. And the majority of people on that poll thought that my thinking was absurd.

Of course I do.

Only for people that I know or I'm well-acquainted with.

I say Gesundheit due to the fact that I'm Athiest. :p Lol although my mom is Catholic and says it both ways.

It's more of an automatic reflex anymore. It doesn't really seem to serve any purpose other than to call even more attention to the sneezing person, but I still end up saying it.
