A school head was alerted by the caretaker to a persistent problem in the girls lavatories: some of the girl students were leaving lipstick kisses on the mirrors. The caretaker had left notices on the toilet walls asking for the practice to cease, but to no avail; every evening the caretaker would wipe away the kisses, and the next day lots more kisses would be planted on the mirror. It had become a bit of a game. The head teacher usually took a creative approach to problem solving, and so the next day she asked a few girl representatives from each class to meet with her in the lavatory.
“Thank you for coming,” said the head, “You will see there are several lipstick kisses in the mirrors in this washroom..”
Some of the girls grinned at each other.
“As you will understand, modern lipstick is cleverly designed to stay on the lips, and so the lipstick is not easy at all to clean from the mirrors. We have therefore had to develop a special cleaning regime, and my hope is that when you see the effort involved you will help spread the word that we’d all be better off if those responsible for the kisses use tissue paper instead of the mirrors in future..”
At this point the caretaker stepped forward with a sponge squeegee, which he took into one of the toilet cubicles, dipped into the toilet bowl, and then used to clean one of the lipstick-covered mirrors.
The caretaker smiled. The girls departed. And there were no more lipstick kisses on the mirrors.
