According to a news report, a certain private school in Washington was recently faced with a unique problem. A number of 12-year-old girls were beginning to use lipstick and would put it on in the bathroom. That was fine, but after they put on their lipstick they would press their lips to the mirror leaving dozens of little lip prints. Every night the maintenance man would remove them and the next day the girls would put them back.
He took out a long-handled squeegee, dipped it in the toilet, and cleaned the mirror with it.
Since then, there have been no lip prints on the mirror.
There are teachers and then there are educators.
