Out of food supplies

With four daughters and one son always dashing to school activities and part-time jobs, our schedule was hectic.
To add to this, we kept running out of household supplies.
I instructed them all to let me know when they used the last of any item by writing it down on a note pad on the refrigerator.
As a reminder, I wrote at the top: "IF WE ARE OUT OF IT, WRITE IT DOWN."
When I checked the pad a few days later, to my delight I found the following message:
"MOM, YOU MAY BE A BIT OLD-FASHIONED, BUT YOU ARE NOT 'OUT OF IT."'
