...or is it just DH?
I always know that I'm going to sneeze, hold my breath waiting for it (and get that sharp tingling in my nose if it doesn't happen).
DH, OTOH, will do an enormous "WAAAASHOOOO!" noise (like people used to do at school, presumably to get attention), then look astonished and say, "What was that?" or "Where did that come from?".
I patiently explain that "that" was a sneeze and they're quite common.
I used to say "Your nose/mouth, obviously" to the "where did it come from question", but last time explained that the sneeze-stork must have brought it.
This bit of sarcasm went down badly, but really!
Do sneezes always take anyone else by complete surprise Every Bloody Time?
PS He also always seems to have had any symptoms that I mention having ("Oh! I've had a dicky stomach too" or "That's odd because I've noticed a bit of a headache myself") and then goes on about them (when I want sympathy, despite having not mentioned them or appeared to have any problems right up until then).
