Opinion: Question that upset my wife

So I just got home after a long 10 hours shift. I go to the kitchen and I don't see any pots or pan and everything is clean. There was a dish of soup waiting for me. So I ask my wife

Sorry not sure why all of the post didn't show. You made me laugh Susie. I Asked my wife if she cook it. And she got all upset and offended by the question. Did I say something wrong?
