Anything

As a wife, I cook at home almost everyday.  When I cook, if there is Adam at home I always ask him what he wants to eat.  He sometime helps me with his ideas about what to eat that evening, but most of time he says "anything's fine".  Here is the thing.  What exactly does this "anything" mean? 

Anything means anything to me, which means "anything".  Whatever I want, I have, I can cook, or to me that's anything that we can eat.  By saying "anything", I take he leaves all process of cooking decision to me.  So I decide.  Normally, when I decide after he said "anything", it is easy Japanese food that I can cook without going to HyVee to get ingredients.  Onigiri and Miso Soup(sounds yummy),  Cha-han and egg drop soup, Udon and vegetable, stuff like that. 

But his answer is always "I don't wanna eat any of those".  

And I think in my head, " Wo, Wo! Didn't you just say anything's fine?" 

He suggests something else, usually it's American food after I suggest my "anything".  He does have preference for what he eats for supper.  But it's almost impossible to pull that answer from him with first question.  Why is that? 

I just finished my supper for the night by myself.  When he works evening, I usually make "anything" supper.  Today I made Tofu with okura, green onion, ginger topped with katsuobushi and ponzu.  Wow, it was amazing.  To me, anything supper is always tasty. 

To figure what Adam's anything mean, I will keep track what we end up with each day.  Man, even 2 years after we got married there are till tons of stuff to learn about each other.
