I just have a little raw flour on the counter I spent 6k building a pizza oven last spring. If I knew she was going to freek about a little flour that I will clean up anyway I might not have built it. I love it but not worth the stress.
That's a shame. If I'm making pizza for your family or friends, then you can help me clean up the mess dear. I suspect she is mad at you for some other underlying issue(s). People often supress their emotions and allow resentment to build, which ends up coming out as an argument over flour on the counter or a sock that didn't land in the laundry basket.
My very first pizza didn't rise at all. I'm glad I kept at it through the failures. Occasionally when I'm tired or in a hurry I will mismeasure or forget to put a topping on. These days I try to just laugh at my mistakes.
