DAE get very angry over very small things?

I grew up and live in the south in an area where we call the evening meal “supper” and the noon/afternoon meal “dinner”. My husband refuses to say supper and calls our evening meal dinner. And noon meal lunch. And all of our kids except my oldest two from previous relationship do too! It’s so small and stupid but it infuriates me! I honestly still get confused everytime he asks what’s for dinner bc in my mind he is talking about a meal that’s already happened.
