So I asked/told my oldest daughter to vacuum the front room, and she grumbled. I ignored it. I continued picking up the dining area. When she was finished with the front room, I asked/told her to vacuum the dining area. They are part of the same room - same carpet.
She said, "No! I just vacuumed in here! (pointing to the front room).
I said, "It's not going to kill you to do a little more."
She said, "Yes it will!"
Didn't miss a beat.
"Good," I said, "then I won't have to hear the grumbling anymore."
Annoyed but grinning in spite of herself she moaned, "Mo-ooooom."
