Bless You!

Ok, so I had to share a funny moment......
This is an excerpt of a conversation had by me and my wonderful husband on our drive home from a birthday party today:

R: Thank you.
Me: What?
R: Thank you.
M: For what?
R: (getting irritated) You just said 'Bless you', so I'm saying 'Thank you.'.
M: What? Did you sneeze?
R: [chuckle]
M: Did I SAY 'Bless you'?
R: Yes. What kind of drugs are you taking?
M: I'm not taking drugs, honey. I'm just deliriously exhausted.

We both had a good laugh. I swear, I do not remember the sneeze, nor do I remember my evident "automatic" response to said sneeze.
