I have pretty horrific allergies and at some times during the year, I SNEEZE SNEEZE SNEEZE SNEEZE SNEEZE without even that much typographic in between. I think it's lovely when people bless me because regardless of their, or my, ecumenical or personal view of the thing, a 'bless you' is kindly meant. I have said at times, when my sneezes were one after another out-of-control, "You don't have to bless me every time, thanks!"
(I've been doing allergy shots for the last 5 months so that I can, y'know, BREATHE, but those are still in progress and in the meantime - well, I'm happy to hear it b/c I think it's kindly meant.)
