(My mother is extremely sensitive to noxious gases. She is the proverbial canary in the mine. My father just installed a new gas stove.)

Dad: “[Mum], can you come to the kitchen, please?”

Mum: “Why?”

Dad: “Just come, will you?”

Mum: *entering the kitchen* “What?”

Dad: *pausing for a moment* “Do you feel well?”

Mum: *puzzled* “Yes, why?”

Dad: “No headache?”

Mum: “No, should I?”

Dad: “Nope, the stove is installed and ready for use…”

(It then dawned on Mum why she had to enter the kitchen and she left in a huff. For clarity, if my dad wasn’t sure it was installed properly, he would never have turned on the gas or risked my mother’s health. It was just to be 100% sure.)
