My mother is a cleaning fanatic.
One Saturday she told me and my brother to get down to the playroom and straighten it up. We had a party there the previous evening, and she was none too happy about the mess.
As she watched us work, it was clear that Mom was completely dissatisfied with our cleaning efforts and let us know it.
Finally my brother, exasperated with having to do it all over, reached for a broom and asked Mom, "Can I use this, or were you planning to go somewhere?"
